The Sheppard and Enoch Pratt Hospital, known to many simply as Sheppard Pratt, is a psychiatric hospital located in Towson, a northern suburb of Baltimore, Maryland. Founded in 1853, it is one of the oldest private psychiatric hospitals in the nation. Its original buildings, designed by architect Calvert Vaux, and its Gothic gatehouse, built in 1860 to a design by Thomas and James Dixon, were designated a National Historic Landmark in 1971.
