Main Street Market Square Historic District contains Houston's best concentration of late 19th and early 20th century commercial buildings. Approximately half of the district's historic structures were built before 1900. Also located within the district are Allen's Landing and Market Square two of the most historic sites in Houston. The buildings in Main Street Market Square range from modest mid-19th century brick commercial buildings to a number of small but ornately detailed High Victorian commercial buildings and include a fine selection of multi-story public bank and office buildings. Main Street Market Square became a City of Houston historic district in 1997 and is also listed in the National Register of Historic Places.
