Bones in a Broch

Iron Age Roundhouse in Scotland, with human burial
Now in Scotland, there isn't/wasn't a lot of wood, so Iron Agers had to build their roundhouses out of stone, not wattle-and-daub. Guess there was a wattle shortage, too. Anyway, a stone roundhouse is called a "broch," which you probably have to be Scots to pronounce. This one at Caithness turns out to contain some human remains, but they may have been put there long after the broch was built, because it was considered a sacred space even centuries after it fell into disuse.
