Hawthornden Castle comprises a 15th-century ruin, with a 17th-century L-plan house attached. The house has been restored and now serves as a writer's retreat. Man-made caves in the rock beneath the castle have been in use for much longer than the castle itself.
The castle comprises a roughly triangular courtyard, approximately 24m long and 12m at its widest point, projecting north-west along a rocky promontory on the south bank of the River Esk. The 15th-century tower is situated at the south-east corner. Around 8m square, the tower is ruined, although the recent renovation included the installation of a library in the tower basement. There is also a rib-vaulted pit prison beneath the tower. Windows on the south curtain wall show that a range of buildings once stood here, although these are now all gone. A well in the west end of the courtyard supplied the castle's water.
The 16th century range is to the north, and is linked to the tower by a 16th-century wall, in which is the entrance. The range is of three storeys and an attic, and was originally harled. The renaissance-style doorway is of later date, as is the iron knocker with the initials of Sir William Drummond (the son of the poet) and his wife, Dame Barbara Scott. There are three gunports around the doorway, with a fourth in the tower. The last addition to the castle was a single-storey range to the west, built in the late 18th or early 19th century.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
