The earliest surviving mention of the lake is in the 9th century
Vita tripartita Sancti Patricii, in connection with the crossing of the lake by
Saint Patrick on his way to destroy the idol
Crom Cruach. In medieval times Garadice Lough was known as Lough Finvoy (
Irish:
Loch Finn Mhagh, meaning 'The Lake of the White Plain'). The lake is mentioned several times in the Irish Annals-
Annals of the Four Masters 1386 and
Annals of Connacht 1257 & 1418. In about 1257 the fortress "
Cloch-inse-na-dtorc, in Lough Finvoy, was burned by O'Rourke" (a King of
West Breifne). ==See also==
