This is a must see. Go before you visit the Alamo to see the diorama of what the entire Alamo site looked like. Phil Collins, the rock star is part owner of the shop. He has the largest private collection of Alamo memorabilia and works with the Alamo and local historians. Check out the excavations that have been done under the shop through a plexiglass viewing window. The diorama was created by an author who was working on a history of the Alamo. Collins, according to the talk he gave which I attended, bought it to place in the shop because it was the most historically accurate created. The vintage documents and maps are fascinating as well.
