Glendalough, is a glacial valley in County Wicklow. It is renowned for its Early Medieval monastic settlement, founded in the 6th century by St Kevin, a hermit priest.
Lough Tay (otherwise known as the Guinness Lake) sits in the Wicklow Mountains of southern Ireland.  It earned its nickname because it borders a large estate owned by the Guinness family.  The colour of the water is such a rich brown (similar to Guinness) that the family imported the white sand on the shoreline to make it look like frothy head on a pint.

Famous film locations include PS I love You, Braveheart, and The Vikings.
