Vandals damage Mission San Juan a 3rd time
Carvings inside main gate likely have caused permanent harm, unlike previous incidents. By Abe Levy - Express-News
For the third time in recent years, Mission San Juan has been defaced by vandals, who this time likely caused permanent damage to an 18th-century stone wall.
National park rangers discovered seven graffiti carvings Friday in the wall just inside the main gate near the convent building.
Moved to its present location in 1731, San Juan is one of four cherished San Antonio missions visited by about 1.7 million people each year from around the world.
