to serve the community and the dock area. Northern Boulevard was developed into a commercial and cultural hub, and the Little Neck Theater, a 576-seat movie theater, was opened in 1929 at the intersection of Northern Boulevard and Morgan Street. The theater was closed in 1983. From the 1860s through the 1890s, small hard clams (quahogs) from Little Neck Bay were served in the best restaurants of New York and several European capitals. Eventually, the term "littleneck" or "littleneck clam" came to be used as a size category for all hard clams, regardless of origin. 20th century In the early 20th century, the Rickert-Finlay Realty Company of Manhattan purchased of the Douglas' family holdings, and formed the Douglas Manor Association, creating a planned community. Many of the houses in this area were built in architectural styles popular at the time, such as Tudor, Mediterranean, Colonial Revival, and Arts and Crafts. In 1997, New York City's Landmarks Preservation Commission designated Douglas Manor as the Douglaston Historic District, ensuring that no new buildings or external alterations could be made without the commission's approval. The Douglaston Historic District was listed on the National Register of Historic Places in 2005. An old Matinecock cemetery remained on Northern Boulevard between Cornell Lane and Jesse Court. One of the last photographs of the cemetery was taken by the Daily News in August 1931, a few months before it was removed to make room for a widened Northern Boulevard. The remains from the cemetery were moved to the Zion Episcopal Church of Douglaston and placed under a stone marker that reads "Here rest the last of the Matinecoc." Other areas of Douglaston–Little Neck were developed during the latter half of the 20th century. Douglaston Park contains a mixture of large, older homes as well as Capes, Tudors, and ranch-style homes dating from the 1960s. The areas adjacent to the Douglaston Shopping Center are occupied mainly by attached single-family homes built in the 1950s through 1970s (Beech Hills, Deepdale, and another development known colloquially as the "Korvette's Houses" due to the former proximity of an E.J. Korvette department store), as well as four-story condominiums added in the mid-1980s. In addition to the Douglaston Historic District and Douglaston Hill Historic District, the Allen-Beville House and Cornelius Van Wyck House are listed on the National Register of Historic Places.
