San Antonio, Texas has five unique Spanish colonial mission churches built in the early 1700's. Each is a real architectural jewel in its own way. The interiors are dark, but some have original decorative wall painting. They are located within a few miles of each other along the San Antonio river. An aquaduct connected the missions and parts of the aquaduct remain intact. There also is a mill at one of the sites. You can find out many more details on the internet. Don't be confused by some of the websites. The local baseball team is called the "San Antonio Missions"! There is a fundraising campaign underway to restore the missions over the next 5 or 6 years. Hopefully the restorations will not take away the character.
