A couple of blocks from Houston's visitor center is this park, which serves as a repository for eight of Houston's oldest houses and buildings, moved here from their original locations. The oldest dates from before Texas's independence; it's a small, simple cabin originally built close to where NASA is today. Another house was built by a freed slave in 1870. There's a church dating from 1892. The Heritage Society restored them to their original state and furnished them with pieces from the appropriate eras. The only way to see these buildings is by guided tour, which leaves every hour on the hour from the tour office at 1100 Bagby; it takes about 45 minutes. The guides are well informed and add a lot to a visit here. The Heritage Museum can be visited without taking the tour. It's free and features permanent exhibits on Texas history.
