Maes Howe (also written as Maeshowe) is a megalithic complex built on the Scottish island of Orkney in the Neolithic period (around 3000 BCE) and part of the UNESCO World Heritage Site the Neolithic Heart of Orkney.
Maes Howe is located about ten kilometers west of the main town of Kirkwall, halfway between the Loch of Harray and Tormiston Mill (the information center) on the A965 road. The Passage Tomb is located on a round oval platform carefully carved out of the rock, which is enclosed by a ditch and wall in the manner of a henge. Maes Howe gave its name to the Maeshowe-type megalithic sites that only appear on the Orkney. The Maeshowe Chamber faces the sunset on the day of the winter solstice.
