from Logan Circle in December 2000. No full grocery store was in the area. It was developed on a site previously occupied by an abandoned service garage; it is now one of the chain's highest-grossing markets. Gentrification in Logan Circle has resulted in a dramatic change of neighborhood demographics; since the 1990s, thousands of White young LGBT and hipster adults have moved into the neighborhood, while thousands of Black families have moved out because of rising prices. Landmarks Logan Circle Historic District The Logan Circle Historic District is an eight-block area surrounding the circle, containing 135 late-19th-century residences designed predominantly in the Late Victorian and Richardsonian Romanesque styles of architecture. The district was added to the National Register of Historic Places on June 30, 1972. The former home of Mary McLeod Bethune, an African American educator, author, and civil rights leader who founded the National Council of Negro Women, is located at 1318 Vermont Avenue NW, one block south of the circle. The Second Empire-style building is a designated National Historic Site and houses the Mary McLeod Bethune Memorial Museum and the National Archives for Black Women's History. Fourteenth Street Historic District In addition to the Logan Circle Historic District, the neighborhood includes the much larger Fourteenth Street Historic District, added to the NRHP in 1994. The district's approximately 765 contributing properties are considered historically significant because they represent residential and commercial development resulting from one of the earliest streetcar lines in Washington, D.C., the Capital Traction Company's 14th Street line, built in the 1880s. The oldest house of worship in the Fourteenth Street Historic District is Luther Place Memorial Church, built 1870–1873, an ELCA Lutheran church situated on the north side of Thomas Circle. Originally known as Memorial Evangelical Lutheran Church of Washington, D.C., the building was renamed in 1884 after a bronze statue of Martin Luther was installed on the church's property. Luther Place Memorial Church was added to the National Register of Historic Places on July 16, 1973. The Gladstone and Hawarden, designed by architect George S. Cooper in 1900, are early examples of Washington's middle class apartment houses. Named for U.K. Prime Minister William Gladstone and his estate Hawarden Castle, they are the first documented twin apartment buildings in Washington, D.C. The Gladstone and Hawarden were added to the NRHP on September 7, 1994. Local landmarks The District of Columbia Inventory of Historic Sites includes several
