North Rona Lighthouse is located around 44 miles northeast of the northern tip of Lewis.
The island is the most remote island to have been permanently inhabited.
North Rona is often confused with the island of South Rona near Skye.
Saint Ronan is said to have lived on the island in the eighth century, and the island was inhabited until 1680 when rats reached the island, and food supplies were raided. It was later populated again, but the final settlers left in 1844.
The ruins of St Ronan’s Chapel can still be seen on the island.
