What is recorded here
St. Patrick's Island in County Dublin held an early Christian monastery for St. Mochonna, marked by a roughly circular enclosure about 75 metres across. Danes burned the monastery in 798 after breaking the shrine of Dochonna, yet the island still bears the faint outline of that sacred boundary. The violence did not erase the place; it sharpened the memory of what people valued enough to lose.
Early Christian monastery associated with St. Mochonna (Doconna, or Conna), venerated on the 13th of January. The Danes are recorded to have burned the monastery in 798 when the shrine of Dochonna was broken (D'Alton 1838, 223). Recent aerial photography of St Patrick's Island (Inis Pádraig) shows traces of a roughly circular enclosure around the church (diam. c. 75m; OS 8/9269) (DU005-019002-).
