A hoard or hoarding (also known as a brattice or brettice, from the French bretèche) was a temporary wooden shed-like construction that was placed on the exterior of the ramparts of a castle during a siege to allow the defenders to improve their field of fire along the length of a wall and, most particularly, directly downwards to the wall base. The latter function was capably taken up by the invention of machicolations, which were an improvement on hoardings, not least because masonry does not need to be fire-proofed. Machicolations are also permanent and siege-ready.
It is suspected that in peacetime, hoardings were stored as prefabricated elements. Construction of hoardings was often facilitated by putlog holes, sockets that were left in the masonry of castle walls for wooden joists called "putlogs". However, some hoardings were supported on permanent stone corbels.
Some medieval hoardings have survived, including examples at the north tower of Stokesay Castle, England, and the keep of Laval, France. The Château Comtal at Carcassonne and the keep at Rouen Castle, both in France, have reconstructed wooden hoardings, and also Castell Coch in South Wales, which was wholly rebuilt in 1875 and has a hoarding over the drawbridge, designed by the Victorian architect William Burges. Another reconstructed hoarding can be seen at Caerphilly Castle, also in South Wales, which extends along the northern curtain wall of the inner bailey.
