The site of an early medieval burial ground associated with the early monastic settlement on St Patrick’s Isle. The earliest recorded remains are two lintel graves in the south transept of the cathedral. They were found in the only undisturbed area uncovered, and they were probably part of a larger cemetery which was disturbed by Medieval levelling and later burials. They are of 5th - 8th century date and confirm the tradition that Peel Island was the site of an early ecclesiastical community founded by St German, who died about 476 AD.
