King Orry's Grave - Credit: Wikimedia Commons
King Orry's Grave is the largest megalithic tomb on the Isle of Man. It is situated in Minorca, in the northern part of the village of Laxey, partly in a private cottage garden. It is some 4000 to 5000 years old; however the reference to King Orry is to the 11th century local ruler Godred Crovan, who has a number of supposed burial places. The modern name likely dates to the early 19th century. Read more on Wikipedia
