File:Old Market Square, Houston.jpg
In 1840 Houston's first municipal market house was built here. Before it was completed, city officials voted to enlarge it and include a city hall also. For 30 years building served dual role-- the market overflowing till it reached the streets. Many items, including household and farm goods, were sold here.
It was here that Houston Independent Light Guard mobilized after Texas decided to invade Mexico, 1842.
Several municipal buildings occupied the site following original market-city hall. However, the seat of city government was eventually moved to a new location and this became a park.
