King Orry's Grave is the largest megalithic tomb on the Isle of Man.

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.

Like Cashtal yn Ard, the structure is a multi-chambered Clyde cairn of coloured sandstone.

As the central section is not extant, it is unclear whether this is part of the same structure as the construction of modern housing has made excavation difficult.

These standing stones likely formed part of a cairn of rubble that covered the burial chambers, similar to those found in the north of Ireland and south-west Scotland.
