About the Harmondsworth Barn

Rescued by English Heritage after years of neglect, this Grade I listed barn ranks alongside the Houses of Parliament and Westminster Abbey for its exceptional architectural and historic interest. It was dubbed the "Cathedral of Middlesex" by Sir John Betjeman.

Built in 1426 by Winchester College as part of its manor farm at Harmondsworth, the oak-framed barn is an outstanding example of medieval carpentry and contains one of the most intact interiors of its era. At nearly 60 metres long, 12 metres wide and 11 metres tall, with 13 massive oak trusses holding up the roof, both its size and aisles evoke the space and shape of a cathedral.

IMPORTANT - Although venues are reopening, their hours may differ from normal, and most now need prebooking before you visit.
