The Deceangli or Deceangi (Welsh: Tegeingl[1][2]) were one of the Celtic tribes living in Britain, prior to the Roman invasion of the island.
[4] They lived in hill forts running in a chain through the Clwydian Range and their tribal capital was Canovium.
[5] Assaults on the British tribes were made under the legate Publius Ostorius Scapula who attacked the Deceangli in 48 AD.
[4] No Roman town is known to have existed in the territory of this tribe, though the auxiliary fort of Canovium (Caerhun) was probably in their lands and may have had a civilian settlement around it.
Roman mine workings of lead and silver are evident in the regions occupied by the Deceangli.
