So, part of the fun of travel and Language is understanding history and influences. This 12th century Abby near an area called The Burren on the Western coast of Ireland, essentially a limestone and somewhat barren region, as the water sinks through as the soil has long eroded from the seaside wind, sun, and shale/limestone bedrock.
I'm not sure, but I think the plaque naming the site means St. Mary of the Fertile Rock. As a gardener, that's a hopeful thought! In the last picture you can clearly see the contrast to the blue sky, the soil-less hills, and the heather growing near the gravesite.
