|SS Mission Purisima (War Shipping Administration)
Mission La Purísima Concepción - is a Spanish mission in Lompoc, CA. It was established on December 8, 1787 (the Feast of the Immaculate Conception, hence the
mission's name) by the Franciscan order. The original mission complex south of Lompoc was destroyed by an earthquake in 1812, and the mission was rebuilt at its present
site a few miles to the northeast. (Wikipedia)
