The Medina Dam, the fourth largest in the nation when completed in 1913, is listed on the National Register of Historic Places.  The irrigation project, creating Medina Lake, was built by 1500 skilled workers who worked in shifts operating 24 hours a day to complete the dam in two years.
The Texas Legislature formed Medina county on February 12, 1848 and enlarged it on February 1, 1850 using land taken from Bexar County. Castroville was the county seat, and the county erected the first permanent courthouse there in 1854. The county seat moved to Hondo in 1892, and a new courthouse was completed there in 1893.
