The Iron Age hill-fort at the summit of this prominent dome-shaped hill is said to have been the ancient capital of Lothian. From it in 1919 was unearthed the Traprain Treasure, about 160 pieces of mainly of mainly fifth-century Roman silver, probably the buried loot of a robber, now in the Museum of Scotland, Edinburgh.
There is a new, rather pricey book coming out. The images are simply stunning and the finds shed new light on the context of Traprain from Bronze Age through to the Iron Age. Maybe one for the Santa wishlist.
