Clwydian Range in the context of Llandegla

The Deceangli or Deceangi (Welsh: Tegeingl) were one of the Celtic tribes living in Britain, prior to the Roman invasion of the island. The tribe lived in the region near the modern city of Chester but it is uncertain whether their territory covered only the modern counties of Flintshire, Denbighshire and the adjacent part of Cheshire or whether it extended further west. They lived in hill forts running in a chain through the Clwydian Range and their tribal capital was Canovium.

Assaults on the British tribes were made under the legate Publius Ostorius Scapula who attacked the Deceangli in 48 AD. 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.

The Clwydian Range and Dee Valley (Welsh: Bryniau Clwyd a Dyffryn Dyfrdwy) is a designated Area of Outstanding Natural Beauty (AONB; also known as a National Landscape) located in north-east Wales, covering the Clwydian Range (Welsh: Bryniau Clwyd), and the valley of the River Dee (Welsh: Afon Dyfrdwy).

Designated in 1985 as the Clwydian Range AONB, and expanded to its current extent in 2011, the Area of Outstanding Natural Beauty includes: medieval field systems, open heather moorland, prehistoric hillforts, limestone crags, broad leaved woodland, wooded valleys, and farmland.
