Severn River (Maryland)

NSS Annapolis, officially known as Naval Communications Station Washington, D.C. Transmitter or NavCommStaWashingtonDC(T), was a Very Low Frequency (VLF) and High Frequency (HF) transmitter station operated by the United States Navy. It was located at Greenbury Point, in Anne Arundel County, across the Severn River from Annapolis, Maryland at coordinates 38°58′40″N 76°27′12″W. NSS Annapolis was used by the USN for submarine communication. The station consisted of an umbrella antenna supported by a 1,200-foot (365.76 m) high central mast, which was insulated against ground, 6 guyed masts of 800-foot (243.84 m) all of which were built in 1969 and three 600-foot freestanding towers built earlier. Originally the station consisted of nine 600-foot-tall self-supporting lattice towers, the tallest of their kind built in the United States to that date. The first four of which were built in 1918, followed by two more in 1922 and the final three in 1938. As of 2020, only the three built in 1938 remaining standing. The huge towers were a local landmark, and served as a visual reporting point for aircraft landing at the nearby Baltimore-Washington International (BWI) airport. A golf course runs through the former HF antenna farm; special rules addressed hitting a tower with a ball (usually stroke and distance). The NSS HF receiver station, and the headquarters for NavCommStaWashingtonDC(T), was located at the Naval Communications Station in Cheltenham, Maryland until 1969. In late 1969, the receiver station at Cheltenham closed and a new receiving station was activated at Sugar Grove, West Virginia. NSS began transmitting in September 1918 using a pair of Federal Electric 500 kilowatt Poulson Arc transmitters. However, arc transmitters were significantly inferior to the then state-of-the-art Alexanderson alternator and one of the arc transmitters was replaced by a more modern TAW 300 kilowatt vacuum tube transmitter in 1931. VLF, or "longwave" radio was the standard at the time for long-range radio transmission, only to be replaced by shortwave in the early 1930s. VLF later became essential for communicating with submerged submarines, a critically important capability as submarines became strategic missile platforms. The NSS transmitter fed one million watts of radio energy to its antenna, and during idle times, transmitted the string "W W W VVV VVV VVV DE NSS NSS NSS" in Morse code. The power was so high and the frequency so low, one could hear the signal on practically any kind of receiver anywhere in the Annapolis area. Messages were also sent in Morse code, but were either prearranged code signals or were encrypted. Rendered obsolete by satellite technology and the end of the cold war, NSS ceased operation and all of the antennas and most of the towers were demolished in 1999. Three of the smaller 600-foot towers were preserved near the tip of Greenbury Point to serve as aids to navigation for boaters on the Chesapeake Bay. The callsign, operating from Annapolis, was brought back for the May 8, 2021 Armed Forces Day radio test. This is an annual event when amateur radio operators can work through crossband communications with certain military stations. However the station was active for only 16 hours.

Sparrow's Beach was a beachfront resort on the Chesapeake Bay that catered to African American patrons during segregation in the American South.Located just south of Annapolis, Maryland, Sparrow's Beach was established as a recreational area during the Jim Crow-era when African-Americans were denied entry into 'Whites-only' establishments. Other nearby beachfront resorts used for this purpose included Carr's Beach, Elktonia Beach, Bembe Beach, Highland Beach, Venice Beach, Oyster Harbor, and Arundel-on-the-Bay.In August 2022, the City of Annapolis purchased what remains of Sparrow's Beach, Carr's Beach, and Elktonia Beach to preserve the land as a park.

Carr's Beach, founded in 1926, was a beachfront resort on the Chesapeake Bay that catered to African American patrons during segregation.Located just south of Annapolis, Maryland, Carr's Beach was established as a recreational area during the Jim Crow-era when African-Americans were denied entry into 'Whites-only' establishments. Other nearby beachfront resorts used for this purpose included Sparrow’s Beach, Elktonia Beach, Bembe Beach, Highland Beach, Venice Beach, Oyster Harbor, and Arundel-on-the-Bay.Carr's Beach was a stop on the Chitlin' Circuit and hosted musical acts like Chuck Berry, Billie Holiday, Duke Ellington, and Ike & Tina Turner.The resort ceased operations in 1974.In August 2022, the City of Annapolis acquired Carr's Beach to preserve it as a park.

The Triton Light is a navigational beacon on the seawall of the United States Naval Academy in Annapolis, Maryland, where the Severn River meets Spa Creek and the Annapolis harbor. It was donated to the Academy and named for the Greek god by the Class of 1945. It is not only an important part of the culture and traditions of the Naval Academy, but also is a trusted navigational point in Annapolis Harbor (e.g., 33 CFR 110.159). About a year after the light was installed, USS Triton (SSRN-586) completed her historic submerged circumnavigation. Considering the coincidence of names, the crew of Triton provided samples of water from the 22 seas through which their boat had passed, which were used to fill a globe built into the light. The characteristics of this light are FL (4+5) G 30s, that is Flashing Green light 4x, then 5x, every 30 seconds. The characteristics of the odd number sequence is unique, an honor to commemorate the Class of 1945. The seawall on the Severn River from Triton Light north-west to the end of Simms Rd at College Creek is exactly 1/2 nautical mile, thus it is frequently used to calibrate speed instruments on boats.

Fort Nonsense is a historic earthen fortification at Annapolis, Maryland. It consists of two arcs of embankments and ditches that date at least to the early 19th century. It is located near 38.9874°N 76.4698°W / 38.9874; -76.4698 on a hilltop which has remained undisturbed by the surrounding Annapolis Naval Ship Research and Development Center. It is the last vestige of Annapolis Harbor fortifications.It was listed on the National Register of Historic Places in 1984.

The Maritime Republic of Eastport (MRE), commonly known as simply Eastport, is a seaside neighborhood community and tongue-in-cheek micronation located in Annapolis, Maryland in the US. The neighborhood was first settled in 1655, and became known as Eastport in 1888, before being annexed to Annapolis in 1951. In 1998, Eastport residents declared independence as a mock secession in response to the Maryland State Highway Administration's temporary shutdown of the drawbridge connecting Eastport to the rest of Annapolis. The micronation hosts numerous fundraisers, including an annual tug of war, 0.05 km (55 yd) run across the aforementioned bridge and annual "Burning of the Socks". The micronation is popular among tourists.

Chance Boatyard is a group of historic buildings at Annapolis, Anne Arundel County, Maryland. It used to be a boat-building and repair complex.

The Wesley Brown Field House is a sports arena at the United States Naval Academy in Annapolis, Maryland. It is located between the 7th Wing of Bancroft Hall and Santee Basin. The 140,000-square-foot (13,000 m2) facility houses physical education, varsity sports, club sports, and personal-fitness programs and equipment. It is home to the Midshipmen women's volleyball team, men's and women's indoor track and field teams, men's wrestling, women’s lacrosse team and sixteen club sports. It also serves as the practice space for the football and women's volleyball teams. There is also a centralized sports-medicine facility. The building has a total room area of 5,800 square feet (540 m2), eight locker rooms, and 300 lockers.The field house has a full-length, 76,000-square-foot (7,100 m2), retractable Magic Carpet AstroTurf football field. When the field is retracted, students can then use the 200-meter AstroTurf track with a Mondo track surface and hydraulically-controlled banked curves and three permanent basketball courts. In four to six hours, the indoor track-and-field can be changed to an indoor football practice field, including target goalposts for placekicking practice. The synthetic playing surface (with football-field yard-lines) is stored on a spool at the field house's south end. The surface is put in place by nine winches and an 18-port air-blower that makes the turf float across the field-house floor while being deployed and retracted.The weight room is one of three "strength and conditioning facilities" at the academy. With 6,500 square feet (600 m2), it serves the members of the following teams: men's and women's cross country, men's and women's soccer, men's and women's track, golf, sprint football, volleyball, water polo, and women's lacrosse.The facility is named for the first African American to graduate from the Academy, retired Lt. Cmdr. Wesley A. Brown, who graduated in 1949. The groundbreaking ceremony was held on March 25, 2006. Brown wielded a shovel in the groundbreaking. Hensel Phelps Construction Company constructed the field house, which was completed in March 2008. The U.S. Naval Facilities Engineering Command (NAVFAC) administered the contract for construction. The building was dedicated on May 10, 2008. Brown participated in the ribbon-cutting ceremony with Chairman of the Joint Chiefs of Staff Adm. Mike Mullen, Naval Academy Superintendent Vice Adm. Jeffrey L. Fowler, and Maryland Governor Martin O’Malley. Also present were almost one thousand guests.

Commodore Uriah P. Levy Center and Jewish Chapel is the Jewish chapel at the United States Naval Academy, in Annapolis, Maryland. The center is named in honor of Commodore Uriah P. Levy (1792–-1862), the first Jewish commodore in the United States Navy, who is famous for refusing to flog his sailors. The Levy Center is adjacent to Mitscher Hall and contains a 410-seat synagogue, a fellowship hall, a Character Learning Center, classrooms, and offices for the Brigade’s social director, the academic board, and the Academy’s Honor Board.Before the chapel was completed in 2005, Jewish midshipmen attended Congregation Knesset Israel in downtown Annapolis, or held services in the interfaith chapel at Mitscher Hall.

Fort Severn, in present-day Annapolis, Maryland, was built in 1808 on the same site as an earlier American Revolutionary War fort of 1776. Although intended to guard Annapolis harbor from British attack during the War of 1812, it never saw action. The United States Navy acquired Fort Severn and two other military bases from the United States Army on 19 October 1845, for the purpose of housing the new onshore United States Naval Academy. The Academy used the structure for classrooms until its demolition in 1909.

Robert Means Thompson Stadium was an American football stadium in the eastern United States, located on the campus of the United States Naval Academy in Annapolis, Maryland. Constructed in 1914, it was the home stadium of the Navy Midshipmen from 1924 through 1958, and was named after alumnus Robert Means Thompson (1849–1930). He created or led several athletically-based organizations at the academy until his death. It was succeeded by the larger Navy–Marine Corps Memorial Stadium in 1959, the current venue of Navy football. Before its conversion to a football stadium, the Thompson Stadium site was an unused area on the south end campus, near the water of Annapolis Harbor. Work on the stadium began in 1914, and was finished later the same year. The seating capacity was 12,000, and it underwent few changes during its entire use. It was surrounded by a regulation quarter-mile (402 m) running track, and only had a single seating section, along the southwest sideline. The field had a northwest-southeast alignment, at an elevation slightly above sea level. During the 1940s, the Naval Academy began to look for options to construct a new, larger football stadium. The school's directors collected money to build the stadium, for which much support was given by the public, due to the lack of seating at Thompson Stadium. Construction on the new stadium began in 1958 and it opened in September 1959. Use of Thompson Stadium ended for varsity games, but it remained until the early 1980s, when it was replaced by Lejeune Hall, the venue for USNA water sports.

Lejeune Hall (sometimes called the Lejeune Physical Education Center) is a sports complex and arena at the United States Naval Academy in Annapolis, Maryland. It currently houses the academy's boxing and wrestling practice arena, and natatorium, and the Naval Academy's Athletic Hall of Fame.
