"Winter Light on Ackergill Tower" - watercolour - 25 x 36 cm
Scotland has many examples of tower houses, dating from medieval times to the 17th Century. They consist of tall, tower-shaped structures, with thick stone walls and small doors and windows. Surrounding the tower there would have been wooden service buildings and maybe a curtain wall or stockade. They were the strongholds of clan chieftains and local warlords at a time when parts of Scotland were fairly lawless.
Ackergill Tower seems a bit unusual to me in that it stands in an area of flat land next to the sea. Usually tower houses were built on rocky promontories or on higher ground. Perhaps the surrounding land was marshy at one time, which would make approach more difficult.
Even if it wasn't good for defence, it is ideal for the present hotel, which stands at the end of two miles of sandy beach, with a view out across the bay.
