[1] The Main Street Market Square District has irregular boundaries.

The district includes all of the blocks between Travis and Main from Texas Street to the northern boundary of University of Houston-Downtown.

From the southern edge of Market Square at Preston Street, it captures all of the blocks northward until Buffalo Bayou.

WL Foley Dry Goods commissioned Eugene Heiner to enlarge the structure in 1889.

Across the street at 201 Travis is the Houston National Bank, once owned by Ross S. Sterling.
