Portencross Castle
Portencross Castle is a medieval tower house on a rocky promontory overlooking the Firth of Clyde at Portencross, Scotland. The present oblong keep dates to the mid-14th century with late medieval additions; it was unroofed in 1739 and restored in the 2010s and now serves as a museum. The site has been fortified since the 11th century and was long associated with the Boyd family.

As it stood in 1730
The shape it held in its prime.
An oblong three-storey stone keep of red-brown rubble with lighter squared quoins, topped by a slightly higher one-storey wing at one end; narrow slit and rectangular windows puncture the walls. The top features a corbelled parapet line and a garret level; the ground floor is vaulted. The castle stands directly on a rocky coastal promontory with the Firth of Clyde visible seaward and a grassy approach on the landward side. At prime the roofs and garret were intact.
Its story
The story of Portencross Castle.
The site at Portencross, on the west coast about 3 km from West Kilbride, has been fortified since the 11th century; in its earliest days it was known as "Arneil" and held by the de Ross family. The present tower is thought to date from the mid-14th century, probably first built as a stone hall house, with upper storeys and an attic added in the late 1400s.
The Boyds retained ownership of the castle until 1737, making further alterations, including upper attic rooms and an extended spiral staircase. A great storm unroofed the tower in 1739 and it gradually became ruinous, though local fishermen continued to use it. Designated a scheduled monument in 1955 and featured in the BBC's Restoration in 2004, it was restored by the Friends of Portencross Castle in the 2010s and is maintained by them as a museum.
