The Peconic River is a river within Suffolk County on Long Island, New York. The river is located in the eastern end of Long Island. The Peconic River drains an area between the Harbor Hill Moraine and flows into Flanders Bay, which in turn connects to Peconic Bay east of Riverhead. The river originates in bogs and wetlands in central Long Island near the Brookhaven National Laboratory and flows eastward to the Peconic Bay. It is the longest river on Long Island and is almost entirely within the Central Long Island Pine Barrens which was set up in 1993 to protect its relative wilderness standing. It is fresh water until about the center of Riverhead where it becomes an estuary. The river is slow-moving, making it ideal for canoeing and kayaking. It forms the border between Brookhaven and Riverhead towns as well as the border between Riverhead and Southampton.

Suffolk County Historical Society Building is a museum and library dedicated to preserving historic artifacts of Suffolk County, New York, as well as other parts of Long Island. It is located at 300 West Main Street as well as Osborn Avenue and Court Street in Riverhead, New York. Though the museum building itself has only been around since 1930, the Suffolk County Historical Society was established in 1886 by residents of the county who were concerned about preserving its heritage. Riverhead was chosen as the location of the new society because it's the County Seat of Suffolk County, and County Surrogate Judge James H. Tuthill became the first President. The society began collecting items almost immediately, and the first displays were placed in a small glass case in Tuthill's Riverhead office. Unfortunately, the collection soon outgrew the Judge's office, and in 1893 a small building at the corner of Griffing Avenue and Main Street in Riverhead, which formerly housed the County Clerk's Office, was purchased. Eventually, the growing collection of documents and artifacts outgrew that space too. The building was designed by August Galow with Colonial Revival styling. It was built on land donated by Alice O. Perkins, the widow of prominent Riverhead resident John Perkins during the 1920s, and was completed in 1930. Extensions were added in 1951 and 1964. The library boasts more than 20,000 volumes and over 840 cubic feet (24 m3) of manuscripts, including records, ledgers, diaries, maps, atlases, post cards, newspapers, and other paperwork. In 1994, the building was listed on the National Register of Historic Places.

The Vail-Leavitt Music Hall is a late nineteenth-century theater presently in use on the east end of Long island in Riverhead, New York. The building was built by David F. Vail, with the help of his son George M. Vail in 1881. David was a local lumber dealer in the Riverhead and Eastern Suffolk County Long Island area. The theater/music hall opened on October 11, 1881. The main theater and its balcony are a miniature opera house designed by J. W. Flack. The ground floor of the building housed commercial business storefronts, while the upstairs contained the opera house. The music hall began its operations with candle lighting, however the Vail's began operating a gas plant behind the theater. As a result, gas fixtures were placed all along the horseshoe balcony, and gaslight continued at the music hall until the advent of electricity to the area in July 1888, when the venue added electric lights. In 1908, George M. Vail, now sole owner of Music Hall, sold the building to Simon Leavitt, a tailor and clothier, who leased out the upstairs as a theatrical venue. In 1914, the Music Hall was used by Thomas Edison as a demonstration site for kinetophone, an early attempt at the synchronization of sound and film. As more modern theaters were built in the area, the Music Hall was converted for use over the years as a restaurant, a roller skating rink and even a betting parlor. However, the balcony and stage proscenium remained intact throughout the conversions. Eventually Theodore Leavitt (Simon's son) took over the clothier business and closed the upstairs, using it only as a storage area until his retirement in the 1970s.After his death, Theodore Leavitt's widow Mollie Leavitt owned the music hall until its acquisition by the Council for the Vail-Leavitt Music Hall in 1982 through a grant from the U.S. Department of Housing and Urban Development arranged by the Town of Riverhead's Community Development officer, Robert Schemer. The Council is a not-for-profit 501(c)3 charitable corporation which now oversees and operates the venue. From the early eighties to the late nineties, old movies were shown on a small screen in its downstairs space, dubbed the "Mini-Cine". These movie showings helped the theater raise monies for the music hall's restoration. The theater has been listed on the National Register of Historic Places since August 25, 1983. The music hall held its grand re-opening on June 28, 2003. It continues to host numerous cultural, civic and charitable events throughout the year for the local community.
