as street names. The area also boasts many fine Victorian-era terraces. These are chiefly located along Victoria Street, which bisects Potts Point from north to south, and is widely known for its impressive canopy of plane trees. 20th century Potts Point was the site of some of Australia's earliest blocks of flats, and from the 1920s through to World War II the area was intensively developed along those lines. As a result, it boasts the highest concentration of Art Deco architecture in Australia. Amongst the most notable examples are the "Macleay Regis", "Cahors" and "Franconia" residential buildings in Macleay Street and "Carinthia" and "Carisbrooke" in Springfield Avenue. Two notable Streamline Moderne buildings in Australia: the Minerva (or Metro) Theatre and the Minerva Building are in Orwell Street. The Metro Theatre (as it was then known) was designed by Bruce Dellit and built in 1940. It was the site of the first Australian production of the musical Hair in 1970, and is heritage-listed. During the Vietnam War, the Darlinghurst Road precinct (commonly known as Kings Cross), which straddles Potts Point and Elizabeth Bay, became a popular destination for US military personnel on R&R – due chiefly to its proximity to a major naval facility. Partially as a result of this, the area attracted organised crime syndicates and developed an unsavoury reputation as Australia's drugs and prostitution capital. Dozens of hotels constructed at the time ensured that "The Cross" remained a tourism mecca well into the 1990s. In 1964, the Rev. Ted Noffs started the Wayside Chapel, an unorthodox Methodist ministry to the Kings Cross area. It began as a small drop-in centre in a block of flats at 29 Hughes Street, and grew into a complex that occupies two blocks of flats. It is a major welfare and community centre in the area. 21st century At the turn of the 21st century, almost all of Potts Point's hotels were acquired by developers attracted by the area's proximity to transportation and amenities. By 2004 most tourist hotels had been converted or rebuilt as expensive unit developments, resulting in a rapid wider gentrification of the area and increasingly large numbers of gay residents that make up a significant portion of affluent same-sex couples in Australia although the continued presence of a number of large and small backpacker hostels in Victoria Street and surrounding streets and dozens of pubs, nightclubs, restaurants and similar venues
