Lauriston Castle is a 16th-century tower house in Edinburgh, Scotland. Currently operated as a luxury hotel restaurant.
The original house was built around 1590 by Lord Archibald Napier of Merchiston (the father of John Napier (1550-1617), inventor of logarithms). It was then acquired in 1683 by the Law of Brunton family of the Law of Lawbridge clan, which later became Law of Lauriston, baronet of Lauriston in Scotland and father of John Law of Lauriston, and marquis of Lauriston in France in the 19th century. The younger branch of this family kept the castle until 1823.
