This fascinating site is what’s left of a baronial hall from the Middle Ages, built by the powerful de Burgh family, Anglo-Norman earls who essentially ruled this region in the 13th century. In the late 1200s, they erected what must have been a lavish hall in which to hold court, receive subjects, settle disputes, and generally live it up in true medieval style. The earls were eventually overthrown by local tribes and the building was abandoned. Time slowly covered any trace of the building, until the foundations were discovered during building work in 1997. You can tour them on glass gangways and view some of the thousands of artifacts that were also unearthed during the excavation.
