Holmead's Burying Ground, also known as Holmead's Cemetery and the Western Burial Ground, was a historic 2.94-acre (11,900 m2) cemetery located in the Dupont Circle neighborhood of Washington, D.C., in the United States. It was founded by Anthony Holmead in 1794 as a privately owned secular cemetery open to the public. The city of Washington, D.C., constructed the Western Burial Ground on the remainder of the city block in 1798, and the two burial grounds became synonymous. The city took ownership of the private Holmead cemetery in 1820. The unified cemetery went into steep decline around 1850, and it was closed on March 6, 1874. Removal of remains, most of which were reinterred at Graceland Cemetery or Rock Creek Cemetery, continued until 1885.

Oak Lawn (later known as the Dean Estate, Temple Heights, and Temple Hill) was a large house and wooded estate that once stood on the edge of today's Dupont Circle and Adams Morgan neighborhoods in Washington, D.C. The estate was bounded by 19th Street, Columbia Road, Connecticut Avenue, and Florida Avenue. Previously called Widow's Mite, the estate was originally several hundred acres, but by the 19th century, had been reduced to around 10 acres (4 ha). The house was built around 1820 and was greatly expanded in 1873 by Thomas P. Morgan, one half of the eponym of the Adams Morgan neighborhood. A large oak tree, nicknamed the Treaty Oak, was reportedly hundreds of years old and stood just a few yards from the house. Oak Lawn was located on a hill. Due to its expansive views of the city, the estate was sought after by local developers. The surrounding neighborhoods evolved into bustling residential and commercial areas. However, Oak Lawn remained a wooded, undeveloped tract until the 20th century. In 1922 the land was sold to a Masonic group who wanted to build a large temple complex. However, due to the Great Depression and a lack of funds, the plan was canceled. In 1940, a local developer selected Frank Lloyd Wright to design a massive mixed-use project there (Crystal Heights) that would include 14 towers and a hotel: that project was also canceled. During the next 20 years, multiple plans for Oak Lawn never came to fulfillment. The Oak Lawn house was demolished in 1948, and the Treaty Oak cut down in 1953. In the late 1950s and early 1960s, the Washington Hilton and two commercial buildings were built on the property that had been home to the old estate.

The Treaty Oak was a 350–400-year-old oak tree that once stood on the Oak Lawn estate in Washington, D.C. The estate was previously called Widow's Mite and owned by the Holmead and Nourse families. It included a large four-story Second Empire house that owner Thomas P. Morgan had expanded. The estate was bounded by 19th Street, Columbia Road, Connecticut Avenue, and Florida Avenue, on the edge of today's Dupont Circle and Adams Morgan neighborhoods. The oak tree earned its nickname due to local legends that a treaty was signed there between early settlers and Native Americans. Despite massive development in the surrounding neighborhoods during the late 19th century and early 20th century, the estate remained a wooded area and was sought by local developers. In 1922 a Masonic group purchased the estate for what was then a significant amount of money to build a massive complex that would include temples. The plans were never carried out, and in 1940 the site was chosen for the large Crystal Heights mixed development designed by Frank Lloyd Wright. That plan was also abandoned. The tree remained until 1953 when it was felled for a planned commercial development. The land where the tree and house once stood is the site of the Washington Hilton, an apartment building, and two office buildings. At the time of its destruction, the Treaty Oak was reportedly the largest oak tree in the Washington, D.C. area.

Crystal Heights (also referred to as Crystal City) was a design by American architect Frank Lloyd Wright for a hotel, apartment, and shopping complex in Washington, D.C. The project would have been built on one of the largest remaining undeveloped tracts in the city, known as the Oak Lawn estate or Temple Heights, on the edge of the Adams Morgan and Dupont Circle neighborhoods. The site was bounded by 19th Street, Columbia Road, Connecticut Avenue, and Florida Avenue, all in the northwest quadrant. One version of the design called for 2,500 hotel rooms, small apartments, parking for 1,500 cars, shops, and a 1,000-seat theater – a diversity of uses almost never seen in structures of the time – all within a complex consisting of a broad base covering the whole site topped by 15 towers. The proposal was defeated primarily by zoning requirements that prevented a multi-purpose structure at the site and forbade towers from rising more than 110 feet. The planned central tower would have been 240 feet high (73 m) and the remaining buildings 14-stories tall. After his design was rejected, Wright heavily criticized local officials and the National Capital Planning Commission. Today, the site is occupied by the Washington Hilton, commercial buildings, and an apartment building.
