San Fernando Cathedral, San Antonio, Texas

The oldest church in Texas holds El Mariachi Mass on Sunday, and is a stunning example of Gothic Revival architecture. But come nightfall, you’d have to be something of a daredevil to enter its myth-ridden grounds. When construction workers started renovating the church in 1936, they unearthed bones, nails, and tattered military uniforms near the altar, which some believe belonged to three soldiers of the Alamo. Since the disturbing incident, visitors have reported shadowy figures and orbs in their photographs, as well as ghosts in the back of the church itself. Such otherworldly inhabitants include a man dressed in black and figures in hooded, monk-like clothing.
