Glendalough is one of the most beautiful historical places in Ireland, whose Irish name means "valley of the two lakes". The monastic city is located at the bottom of a deep and fascinating valley, framed by two dark bodies of water and surrounded by green slopes covered with larches and firs. The beauty of the landscape blends with the mysticism of the ancient monastery founded by St Kevin in the 6th century: here the saint retreated to live as a hermit. The monastery soon became a famous pilgrimage destination, which attracted believers from all over Europe until the 9th century.
