In my last posts, “Inner Ring, at last” and “Inner Ring, look down,” we passed over the entrance to the inner enclosure.

A long path through fields, karst landscapes and outer walls leads to this entrance to the inner ring of Dun Aonghasa (Dun Aengus) of Inishmore, Aran Islands, County Galway, Ireland. The image composition is as a dramatic landscape with the surrounding walls and the cloudscape of an approaching storm.

A view to the northwest from within Dun Aonghasa in springtime. The interior a karst formation (see my post, ” Galway Bay View from Dún Aonghasa”), the grikes (see my post, “Grykes and Clints”) filled with grass and a sprinkling of white and yellow flowers, a cloudscape rising over the walls. Inishmore, Aran Islands, County Galway, Ireland.

Wishing a blessed All Saints Day (November 1st) for all my readers.

From the commanding location of Dun Aonghasa, looking northeast across Inishmore island, we can understand why the ancient builders chose this location.

We also see the transition from exposed limestone to the fields built literally from the ground up (see my post “The How of Soil”).  For a closer view of island houses see my posts “Settled In” and “Cottage Road Cottage.”

The field walls are described in my posts, “What is a rock, what is a stone?” and “Stone on Stone.”

The exposed limestone of the Aran Islands here transitions to a fertile field of grass, husbanded by generations of islanders. Photograph was taken from the path on Inishmore leading up to Dun Aonghasa. 

The Aran Islands are an extension of The Burren of Ireland’s Counties Claire and Galway.  The word burren is from the Irish Boireann, meaning “great rock.”  The glaciers that covered Ireland, retreating about 10,000 years ago, scraped down to the bedrock, exposing wide areas of limestone and dropping, here and there, large rocks.  When people came along the foreign nature of the large rocks was recognized, all the more obvious for lying on the horizontally bedded, exposed limestone.  We call the foreign rocks erratics.  The underlying scoured rock is a pavement for a resemblance to a cobbled roadway.

The incised line, filled with grass and wildflowers, in the following photograph is called a gryke.  The body of stone between the grykes are clints.  Sometimes, the grykes are cross hatched and the clints resemble cobblestones or flat paving stones. 

The view is northeast toward the 12 Bens of Connemara. Inishmore, Aran Islands, County Galway, Ireland
