Glendalough, Gleann da Loch, the valley of the two lakes, is
one of the important religious and historic places in the Wicklow
Mountains. In the 6.th century Saint Kevin appeared in the valley and
founded a hermitage. As Kevin was an excelent scholar, more and more
people pilgered to the valley and a monestary was founded. In the 12th
century Gleandalough was a town with seven churches and about 3000
inhabitants. Numberous Viking attacks and a devastating fire in 1398
brought the learned life to an end.
