Brú na Bóinne: Dark was coming on fast when we finally spotted the mound next door--appropriately, since "Dowth" ("Dubhadh" in Irish) means "dark." It was badly damaged in the 19th century by amateur tomb-raiders in search of treasure, and looks from some angles like a stone quarry--which it was for a time. It is currently being scientifically excavated. It is 46 feet high and 206 feet in diameter. The flash from the camera did little to illuminate the mound, but lit up the overhanging leaves. From the top you could originally see both Knowth and Newgrange, but trees have grown up to obscure the view.
