The Brocas helm is a jousting helm on display at the Rotunda as part of the Tower of London armoury collection.
It was commissioned by an English knight from an Italian armourer.
[1] It is named after the Anglo-Norman Brocas family of Beaurepaire, Hampshire descending from the knight Sir Barnard Brocas (1330–1395).
The collection of the family was auctioned after the death of a later Barnard Brocas, as the "Brocas Sale" in 1834.
