“Here in the 6th century, St. Kevin founded a monastery from which grew the monastic city of Glendalough, which became one of the most renowned centres of learning in Europe. Today the ruins still eloquent of the former glory of the place make Glendalough one of the most interesting of Ireland’s historic sites. The Round Tower is about 110 feet high and 52 feet in circumference at the base, and is still in an excellent state of preservation.” — from the back of the card
This is from the same series as yesterday’s card, so I’m going to date it as 1980, too.
Interment.net says the graveyard surrounding the Round Tower is still in use.
