San Fernando Cathedral. The cathedral was founded on March 9, 1713, by 15 families from the Canary Islands. People from the Canary Islands came to found the city of San Antonio on a special invitation of King Philip the V of Spain. This cathedral is the oldest, continuously functioning religious community in the State of Texas. The cathedral was intended to be in the very center of San Antonio because the the Catholic Church was the only recognized church in Spain and Mexico, and people believed that religion should be the center of your life. Not only being the oldest church in the old state of Coahuila Y Tejas ( Modern day Texas and some parts of north Mexico ) it was also one of the oldest Catholic Churches in America. The church served other historical purposes during the time, most notable being the place where Mexican General Antonio Lopez De Santa Anna hoisted the no-quarter flag during the siege of the Alamo.
