Midhowe Broch information
Lonely Planet review
Next to the Midhowe Tomb is Midhowe Broch, the sturdy stone lines of which echo the stratifications of the rocky shoreline. The best example of a broch in Orkney, it's a muscular, Iron Age fortified compound with a central partition fashioned out of stone slabs, with two hearths, water tanks, quern stones and lots of Skara Brae–style stonebuilt storage shelves.
Dating from around 100 BC, it has a cluster of well-preserved outbuldings, including dwelling houses (you can see the holes for the hinge pins of wooden doors) and a forge for smelting iron.
