Oban,
Scotland
Dunollie castle is built on the headland at the entrance to Oban Bay. The remains consist of a tower house with a courtyard, and traces of a wall circling the summit of the headland. The castle was built in the 12th century, probably by Ewan MacDougall, however the surviving remains of the tower house date from the 15th century. The only remaining portion of the curtain wall, is around 15 feet wide and precariously perched atop the summit.
The castle is visible as you sail into Oban Bay, shrouded in trees and covered in ivy and creepers.
In 1746, the castle was abandoned by the MacDougalls, in favour of Dunollie House just down the road.
The curtain wall, the kitchen and a well are all that now remain of the original 13th century structure.
The castle was re-acquired by the MacLeans in 1911, and was partially rebuilt a year later.
The main ruins that can be seen today, consist of the remains of the Hall house, rising around 32 feet above the sea below it. Traces of other buildings can still be seen on the North side of the hall. There are no defensive earth works at the site, either on the sea ward or land ward side of the castle. It appears that the natural position of the castle was enough to ward off potential attackers.
The surviving walls of the hall house are around 9 feet thick in places, and rise to around 16 feet at their highest points.


The pele portion of the building is a 14th century defensive structure, joined to a mostly 15th century hall. The tower has had some minor rebuilding done to it during the Elizabethan period, namely the addition of windows at the ground floor.
