Kelly Rounds (Castle Killibury) is a bivallate Iron Age hillfort covering 5 hectares near Wadebridge in Cornwall, England. Radiocarbon dating places the main occupation between 400 and 100 BC, while pre-hillfort activity dates to 1250-950 BC. The ramparts stand about 3 meters high externally with ditches cut 2.8 meters into bedrock. Excavations uncovered imported Mediterranean pottery from the 5th-6th centuries AD, and the site is a leading candidate for Celliwig, King Arthur's legendary Cornish court.
