Caer Lêb

Caer Lêb is a Roman and mediaeval site on the Welsh island of Anglesey, west of Brynsiencyn [1]. Its name means "Leaven Castle" [1]. It is a low-lying site near the Afon Braint with a double row of pentangular banks (some parts now levelled) and marshy ditches [1]. The original entrance was on the east [1]. Based on the excavation of a similar site elsewhere on Anglesey, it may date from the 2nd century BCE [1]. Excavations in 1865 found structures within the enclosure, rectangular buildings on the east and a circular one on the south [1]. Nothing of these can now be seen on the ground [1]. Pottery from the 2nd century to the 4th century was found, and on the north side a layer of periwinkle shells and a mediaeval coin, under a layer of peat [1].
