Historic Significance:
During 13th-14th centuries, Restormel was a "miniature palace" rivaling royal residences, with more money spent on maintaining the park boundary than any other feature - reflecting the high value placed on hunting. The castle overlooked Lostwithiel, which became a key administrative centre for Cornwall's tin wealth.
