Once called "Great Head," this rocky outcropping offers sweeping views of the Atlantic Ocean and the mansions perched along the eastern coast of Marblehead Neck. According to the town, the park takes its name from the adjacent castle-like estate and once served as a lookout for enemy ships.
The park can be reached by a pathway from Ocean Avenue. Nearby on-street parking is free but limited to two hours.
