Old County Courthouse
The Old County Courthouse is an historic court house on Leyden Street and Market Street in the Town Square of Plymouth, Massachusetts. Built in 1749, the two story wood frame building is believed to be the oldest wooden courthouse in the United States; it stands on the site of the first courthouse built by Plymouth Colony settlers, and may incorporate elements of a 1670 building. The site was originally the site of Edward Winslow's first house in Plymouth.
It is five bays wide and three deep, with a center entry flanked by sidelight windows and pilasters, and topped by a gabled pediment. It was built by Peter Oliver, and initially served as both a courthouse and as town offices. It was converted to solely municipal use in 1821, and had a myriad of municipal functions since then. In the 1970s it was converted into a museum.
The building was added to the National Register of Historic Places in 1972. It is now known as the 1749 Court House and Museum, and is open from June to September with exhibits of early Plymouth history.
