Blockhouse. Probably 1548-52. Roughly coursed granite rubble.
Rectangular plan. Top of the platform is enclosed by walls,
originally surmounted by a parapet with embrasures. Stairs to
east. Winder stairs to original lean-to in south-east corner,
with plain granite open fireplace; remains of later room
constructed in south-east corner of platform. Covers Old

on Tresco under Sir Francis Fleming, and later John Kiligrew,
captain of Pendennis Castle, between 1548 and 1552. Scheduled
as an Ancient Monument.
