This rectilinear enclosure of double banks and ditches has a complex and sometimes murky history. Its location on low-lying marshland led some to believe that it may once have been a medieval moated homestead, while excavations have uncovered medieval coins and Roman artefacts dating from the 3rd century.
However, it seems that these items were left by the settlement’s later occupants rather than its original builders, with investigations of similar sites elsewhere in Wales suggesting that Caer Lêb has Iron Age origins.
