MonissaBroch of Gurness, on the northern part of the main island of Orkney. Iron Age of course. The central tower was about three times its current height. It surrounded by a small village that was built later (possibly after the broch collapsed or been shortened).
It's forty minutes walk from the nearest bus stop. (I get on the bus and ask for a ticket to Evie? You're going to the broch, asks the bus driver. The second stop is closer and less traffic, he says. He'll drop me at the second stop.) But it doesn't feel like forty minutes and way worth it.
