What is recorded here

Oileán na Muice is a long, ridge-spined islet off the northern coast of Mayo where a stone wall cuts across a narrow neck, suggesting a promontory fort that used the sea as its own defence. Markus Casey later argued the island was once joined to the mainland, making the wall a practical fortification rather than a mysterious marine anomaly. T. J. Westropp dismissed the wall as natural in 1912, but that doubt has lingered because the site remains unmarked, inaccessible and uncertain.
