Unique displays and a general store filled with activities for children bring history to life at the Heritage Museum of Montgomery County. This museum features exhibits chronicling the county's roots, from the lumber and oil industries to the everyday lives of Montgomery County residents and is housed in the historic Grogan/Cochran home, built in 1924. An important feature of the Museum is a replica of the office of Dr. C. B. Stewart, a local resident who served as the first Secretary of State to the Republic of Texas. Dr. Stewart designed the state flag and seal and created original maps of the county. The flag later became the official "Lone Star" flag in 1845 when Texas joined the Union. The museum is also home of the Griffin Papers, dating back to 1831 (can be used as in-house research) and certified copies are obtainable. Handicap accessible and audio tour equipment available.

The museum sports one of the four Joe Roughneck statues, a salute to oilfield workers, in the park beside the museum.
