Patrick Stewart, Earl of Orkney, built it in the early 1600s, and its turrets, oriel windows and tall chimneys still rise above a green lawn a few steps from St Magnus Cathedral. Climb the wide stone stair to the great hall on the first floor, where one of its two fireplaces is five metres across.
Your ticket takes in the Bishop's Palace beside it too, and that one is far older. It was built in the 1100s, at about the same time as the cathedral, and King Haakon IV of Norway died there in December 1263 on his way home from the Battle of Largs. Look up at its round tower, added by Bishop Robert Reid in the 1500s. Both palaces open daily from April to September, with a half-hour break for lunch.
