Millie & I recently visited the Texas City Museum on 6th Street in Texas City Texas.
This museum is housed in the completely renovated home of the J.C. Penney store downtown.
They have many exhibits related to history of Texas City including much about the Texas City Disaster in which the US Grand Camp exploded in 1947. There is much to learn, also, about how the city was discovered and developed in to one of the largest petroleum refining cities in the USA and even a good display of model trains. I would highly recommend a visit if you have any interest. The cost was only $3 each.
