O'Brien's Castle is located on Inis Oirr, one of the Aran Islands off the coast near Doolin, Ireland. It was constructed in the 14th century to protect Galway Bay and the western coast of Ireland. I found it unusual that visitors were free to approach and investigate the ruins. From within the structure one could sense a strong presence of the past.
