The intriguing Earl’s Palace was once known as the finest example of French Renaissance architecture in Scotland. One room features an interesting history of its builder, Earl Patrick Stewart, a bastard in every sense of the word, who was beheaded in Edinburgh for treason. He started construction in about 1600, but ran out of money and never completed it. When it's closed you can still get a good look at it from the garden. Admission includes the adjacent Bishop's Palace.
