Description:
"On our first trip to Ireland, we saw our first round tower at Turlough, just outside of Castlebar in County Mayo. Standing proud on the top of a cemetery ridge, it was visible for quite some distance. That it had survived for well over 800 years was incredible to me." Thoroughly researched webpage.
