An Iron Age fort on a relatively low-lying hillock which is overlooked by a higher ridge to the south, Chesters Hill Fort is located a half mile (1 km) south of Drem and 1¼ miles (2 km) east of Ballencrieff in East Lothian. Two sets of ramparts entirely encircle the site, with three further lines of banks to the north. A series of earthworks stretch across the west and east end, presumably intended to protect the entrances at the northwest and east of the fort. Traces of roundhouse foundations are visible within the enclosed area, some measuring up to 12m (39 feet) in diameter, with several overlying the ramparts suggesting a period of later occupation.
Due its poor defensive position, beneath a high ridge making it vulnerable to attack, it has been suggested that this elaborate hill-fort was built to impress rather than to protect.
Chesters Hill Fort is in the care of Historic Environment Scotland.
