Lauriston Castle is a late 16th century stone rectangular tower house, founded by Sir Archibald Napier. Of three storeys and an attic, the first floor hall is above a vaulted basement and projecting from the north wall is a central stair tower, circular at the base and rectangular above. Corbelled out on the southern angles and rising to the wall-head, are large two storey pepperpot bartizans, complete with gun loops. In the early 19th century, architect William Burn added eastern and northern two storey Jacobean ranges to the tower when constructing of a splendid country mansion. 4 miles south-east is Edinburgh Castle.
