N. Velzer House and Caretaker's Cottage

The John Harned House is a historic house located at 26 Little Neck Road in Centerport, Suffolk County, New York.

Suydam House (also known as Suydam Homestead) is a historic home in Centerport in Suffolk County, New York. It was built about 1730 and is a rectangular, five-bay, 1+1⁄2-story saltbox type building with a one-story wing. It features a steeply pitched, asymmetrical gable roof, pierced by a brick chimney.The house is on Suffolk County Parkland on the southeast corner of Suffolk County Road 86 and New York State Route 25A, across from the southern terminus of Little Neck Road. It was added to the National Register of Historic Places in 1988.The Greenlawn-Centerport Historical Association has restored the house and operates it as a historic house museum. Of particular note are the unusual windows, both six panes over three, and four panes over two. Its NRHP nomination from 1988 asserts:The Suydam house is architecturally and historically significant as a distinguished, largely extant example of settlement period domestic architecture on Long Island that recalls the early growth of the town of Huntington. Built circa 1730, this New England style saltbox (with eighteenth century wing) is one of the oldest remaining houses in the village of Centerport. It is similar in plan, construction and design to many settlement period dwellings in Huntington (Town) such as the John Wood House (circa 1704) and the Ireland-Gardiner Farm (circa 1750). Like these and other seventeenth and eighteenth century dwellings in the Huntington (Town) Multiple Resource area, the building exhibits characteristic architectural features of early construction practices on Long Island, including heavy hewn timber framing, original wrought-iron hardware, and an overall lack of decorative ornamentation.

Arthur Garfield Dove (August 2, 1880 – November 23, 1946) was an American artist. An early American modernist, he is often considered the first American abstract painter. Dove used a wide range of media, sometimes in unconventional combinations, to produce his abstractions and his abstract landscapes. Me and the Moon from 1937 is a good example of an Arthur Dove abstract landscape and has been referred to as one of the culminating works of his career. Dove made a series of experimental collages in the 1920s. He also experimented with techniques, combining paints like hand mixed oil or tempera over a wax emulsion as exemplified in Dove's 1938 painting Tanks, in the collection of the Boston Museum of Fine Arts.

The Mill Dam Bridge carries Mill Dam Road across the tidal mudflat of Centerport Harbor on the North Shore of Long Island, in Centerport, Suffolk County, New York. It divides the navigable waters of the harbor from the Mill Pond formed by its tidegates.The original Mill Dam and tide mill were built in 1674 at a site south of the present location. The bridge at the current location was first constructed in 1774 by Sylvanus Townsend. The mill was dismantled in 1915, and parts of it were used to construct the nearby William Kissam Vanderbilt II estate, which is now the Vanderbilt Museum. The current Mill Dam Bridge prestressed concrete center span and tidegates built in 2005 replaced the span from 1936. The replacement project won the 2005 American Council of Engineering Companies (ACEC) Long Island Project of the Year Award.The bridge was closed to traffic in October 2007, due to deterioration of the old causeway connecting the new span to the shore. In February 2008, workers making repairs to the causeway unearthed a 3000 pound (1400 kilogram) gear, believed to have been installed at the tide mill during an 1848 overhaul. It reopened to traffic on June 27, 2008.

She was restored between 1976 and 1985.She was listed on the National Register of Historic Places in 1986.

Camp Alvernia is a non-profit recreational summer camp in Centerport, New York on the North Shore of Long Island. The camp is located on the east shore of Centerport Harbor, on the Little Neck peninsula. It was founded in 1888 by the Franciscan Brothers of Brooklyn, who still run the facility now, over 130 years later. Alvernia was the first and is now the oldest Catholic camp in continuous operation in the United States.Camp Alvernia is currently a day camp that serves 800-900 children ages 3 to 14 from all religious backgrounds, and also continues to serve as a retreat for the Franciscan Brothers. The Camp offers boating and sailing activities, land and field activities, and swimming in four pools. Scholarships are also awarded each year to families in serious financial need. Originally built as a summer retreat for Franciscan brothers, the 18-acre (73,000 m2) facility later became a residential camp for immigrant children living in New York City, who slept in tents until cabins were built in the 1930-40s. It was originally named "Mount Alvernia" after the mountain in Italy where Francis of Assisi is said to have received stigmata. Funding for the camp was raised by redeeming Kirkman Soap wrappers, each having a value of two cents.Camp Alvernia was founded as a residential camp for boys. It was a co-ed sleep away and day camp as early as the 1980s (possibly earlier). Boys and girls, ages 5–18, could go for either 3- or 6-week periods of time. (Later changed to 2, 4, 6, or 8 week sessions) Girls traditionally stayed in the dorms attached to the main building, brother residences, and the dinning hall; there was one room for younger girls, and one room for older girls. Boys stayed in traditional cabins with names such as Nest, Bayview, Shady Rest, and Seaside that were separated according to their age. There would be a weekly campfire for all sleep away residents. Weekends had offered lot more freedom in terms of activities. At the time of its 100th anniversary, it was still run as a simultaneous residential and day camp. Residential students would be awoken by a reveille over the campus wide loudspeaker, meet for breakfast, and then break into their day camp groups, as the day campers would be bused in from local Long Island towns in vans.Keeping with the camp's theme and location, the day camp named its various age groups after tribes of the Iroquois nation. The youngest campers were called the Oneidas, followed by the Mohawk, Huron, Cayuga and the Senea. The same names are used to this day, although the age groups they refer to have changed. Cayugas are boys and girls who completed school pre-k and kindergarten prior to the start of camp, Oneidas are 1st and 2nd graders, Mohawks are 3rd and 4th graders, Hurons are 5th and 6th graders, and Senecas are 7th-9th graders. Historically children were also further separated within their group designation as girls groups and boys groups; throughout the day, there would be friendly competition within the designation Seneca Nation. Within each particular age group, campers would be assigned to a particular number within their group for instance there was Seneca Girls 1, Seneca Girls and 2, Seneca Girl, 3 a very detailed member of the administration team would assign a daily camp schedule for the day. The activities could include camper choice, soccer, tennis, boating, arts & crafts, dance, swimming, dodge ball, basketball, ping-pong, and for the little ones, many learned to swim for the first time at Camp Alvernia in addition to participation in age-appropriate aforementioned sports and age specific games like parachute, red rover, red-light green-light. In 2016, the camp began accepting three year olds in a new age group called the Pequots.Camp activities included traditional arts and crafts and swimming, but also had full basketball courts, tennis courts, beach volleyball, soccer, softball, and playing fields. Its specialty was boating, especially windsurfing. Campers would have boating, led by the famous Brother Louie, as he gave an all-important safety talk followed by Q&A under the big shady tree on the sandy hill in front of the boat house. He would tell stories and educate all campers on the importance of their PFD - (personals flotation device). This was a square orange life jacket. During the boating period, Brother Louie would name one of his boating specialty counselors skilled in sailing who would stand up, assign the counselor a vessel, and all that were interested in going with that counselor would raise their hands. Brother Louie would select the campers that would go with that counselor, and they would take off down the beach on their way. Lastly Brother Louie would assign the typically age group counselors typically to the campers not selected for sailing. There were many options for campers. They could canoe, kayak (post 2000), windsurf, sail (sunfish boats) or go on the few larger sailboats for a sail ride. Before 2000, there would also be "field trips" excursions to the Commack roller skating rink, Vanderbilt the Museum in Centerport, the local arcade (on rainy days), and nearby beaches (Robert Moses for the older campers and Centerport for the younger campers). Another important nostalgic element of camp was the garage where campers could visit the canteen, and purchase candy soda, little favorites from pocket with the money parents might give them throughout the week. Before 2000, and the loss of records in the 1990s, the Franciscan brothers were a collaborate but competitive athletic group of mentors. Camp Alvernia had a competitive softball team that traveled several times a summer to play against other camps. By 1990 the all-boy softball team recognized female talent and opened up participation up to a few female players (Tonya Cavallaro was their first female pitcher). Overall, the leaders of the camp, both Franciscan brothers and Catherol family did a great job engaging both female and male campers with athletic and non-athletic activities, encouraging participation, and recognizing all campers' accomplishments. They recognized participation in all activities during the day with an elaborate points system accompanied by an elaborate (manual) record keeping system (that was probably lost in the damage that was done as it was before the days of the internet and cloud). Points were awarded for any effort and participation, called "participation points". Counselors were charged with record keeping each day handing in the point sheets. Campers could earn additional points if their particular group won at an assigned activity, such as soccer over another group. For instance, Senaca Girls Group 1 VS. Senaca Girls Group 2. There was even a methodology set out to give points for ties. This point system bonded the individual groups even further as they learned to play fairly, work together, build character, and win and lose graciously. Campers could also earn individual additional points if they placed in the camp marathon or track and field races among all campers of their particular age and gender. All campers would earn participation points for participating.At Friday award ceremonies, 1st to 4th place ribbons were given out for track and field events and the camper of the week in each group would be awarded a button and certificate. These points were cumulative over the course of the summer and impressively, year after year. There were milestones awards for points over cumulative years. The highest recognition of points would be 16,000 A's which would earn the camper a plaque, recognition at the awards ceremony. Along the way, there were chevrons for milestones. This was arguably a great system because even the most athletic camper over time would earn these acknowledgements. This community spirit of cheering on others' various accomplishments was reinforced by the unique clapping system every Alverian clap equaled two claps with a pause. In the 1980s and 1990 One of the brothers, or camp director would typically MC'ed weekly awards. They would ask all to hold their applause until the end and then depending on the age group and accomplishment they would give those campers a respective number of Alvernians. So, they could ask for two and a half Alvernians which would be clap-clap, pause, clap-clap, pause, clap. This would sound impressive coming from several hundred campers in a dome, garage, or even on a hillside depending on where the awards ceremony was held that week. Upon the conclusion of the summer there was excitement and anticipation building up to a full afternoon of awards to conclude the summer. There were awards for every area of camp activity specialty for boys and girls in every respective group from Mohawk all the way to Senaca in the form of a bronze, silver, or gold metal including an overall best female and best male trophy in that category named after a Franciscan Brother. The award recipient was decided upon by the counselors in those respective age groups based on performance throughout the summer. There were categories like boating, arts & crafts, soccer, softball, tennis, swimming, and track & field. The annual awards ceremony for decades ended with camper/athlete of the year, typically awarded to a Senaca the oldest group, someone who was enrolled in the last session of the camp, and typically was there all summer. These were not necessarily requirements but obvious attributes of the winner. These campers were nominated and voted on by all the counselors. There was great anticipation of who would win the prestigious title every year and typically the individuals that were the 12 runner ups and winners were campers of high drive and athleticism. In the summer of 2000, Camp Alvernia developed a course called "Leadership Skills in Community Youth Recreation." The course was based in part on the camp's annual pre-camp orientation program, and participating camp counselors earn college credit. The Love of Learning Montessori method school moved to the grounds of Camp Alvernia in September 2004.In the 1990s, many of the camp's records were thrown out, having suffered water damage. In 2010, the camp began a concerted effort to reconnect with former campers and counselors. In 2012, the camp built two new pools to provide additional space for recreational and instructional swim programs. The camp also conducts a greatly expanded boating program, with paddle boats, canoes, kayaks, stand up paddleboards (SUPs), and sailboats. The camp also offers a sailing certification program through US Sailing.

Centerport is a hamlet and census-designated place (CDP) in Suffolk County, New York, United States, on the notably affluent North Shore of Long Island, historically known as the Gold Coast. Formerly known as Little Cow Harbor in about 1700, as Centerport in 1836, and as Centerport after 1895, the name refers to its geographic position midway between the east and west boundaries of the town of Huntington.As of the 2010 United States Census, the CDP population was 5,508. It is located in the town of Huntington. Huntington and its surrounding hamlets mark the east end of Long Island's renowned "Gold Coast", the name deriving from the traditional wealth and gentility associated with the area. The association dates back to the early twentieth century in which many affluent families built their homes along the north shore of the island. In Centerport, an example of this is the estate of William Kissam Vanderbilt II, otherwise known as Eagles Nest. Centerport is highly residential, characterized by winding driveways and beachfront hills. As is common among the many beachfront locations on Long Island's North Shore, Centerport has developed a large boating and sailing culture. An important part of this culture is the Centerport Yacht Club, which was founded in 1947 and has served as the social and athletic focal point for the boating community in both Centerport and its surrounding areas. The yacht club sponsors a variety of racing fleets and regattas every year generally beginning in the late spring and ending mid-autumn. Suydam House, built in 1730, a saltbox house, is one of the oldest surviving houses in Centerport.
