Hygieostatic Bat Roost
Comfort, TX
Built in 1918, this shingle-style tower was designed to lure and shelter bats so they would devour the mosquitoes then blamed for spreading malaria. It was commissioned by former San Antonio mayor Albert Steves, Sr., on the advice of Dr. Charles A. R. Campbell, a bat authority and city health officer, and was one of only sixteen such roosts built in the United States and Italy between 1907 and 1929.
