Following Zac and his crew in this season, we will visit: Preston Castle, a former reformatory school, Castillo de San Marcos, a 17th-century Spanish fortress, haunted La Purisima Mission, historic Birdcage Theater, decommissioned Eastern State Penitentiary, one of the country's oldest prisons and the secret of a lethal witch and the incubus and succubus, at the Ancient Ram Inn constructed in the 12th century over a heathen burial ground.
