The Downtown Historic District, Inc (DHD) is a non-profit organization, founded in 1991, that serves as an advocate for the preservation and redevelopment of the Main Street / Market Square Historic District in downtown Houston. The Historic District rests between Buffalo Bayou, Minute Maid Park, Houston’s Theater District, and some of the world’s tallest and finest skyscrapers. The District comprises most of the original town plat of Houston as it was laid out by Augustus Chapman Allen and John Kirby Allen, Houston’s founding brothers, in 1836. The area was listed in the National Register of Historic Places in 1983 and declared a City of Houston Historic District in 1997.
The DHD works to build a vibrant, hospitable and diverse neighborhood with a balance of residential, commercial, and arts and entertainment interests. Working with building owners, retail establishments, residents and interested citizens, the DHD focuses continuous attention on business promotion, appearance, parking and amenities, and the use of Market Square Park. Special emphasis is given to the renovation and restoration of historic structures. Support from private foundations, corporate contributions and annual memberships help fund programs to facilitate positive economic development.
