On our way into The Lodge at Ashford Castle we noticed some ruins just off the road. We asked the staff about it and was told that it was Ennis Friary. On our way out we visited the friary. It's address is "Abbey St, Ennis, Co. Clare, Ireland." You and I wouldn't call that a street.

The friary was build in the mid-1200s and went back and forth between the monks and the conquering British for centuries.
