For history or military fans, Fort Sam Houston Museum is a great museum to visit. Focusing on the history of the U.S. Army from its arrival in Texas in 1845 to today, the exhibits are filled with everything from flintlock rifles and old photographs to automatic weapons and uniforms. War videos play on a continuous loop throughout the day and give visitors a glimpse of what the military has done on our country's behalf. Visitors can also wander among the artillery pieces displayed outside.
