Photograph of a view of the twin towers and the cupola of Mission Purisima de Concepcion, San Antonio, Texas, ca.1900. The identical twin towers are approximately three-stories tall. On the corners of the tower are small spires. At right, the cupola peaks above the dilapidated structure before it.; "The Mission Concepcion was established in 1731. One of the most attractive of the San Antonio missions, it took more than twenty years to complete. The massive church with twin towers and a cupola is the oldest un-restored stone church in the United States." -- unknown author.
