A 12th century tower house built by Robert II, King of Scotland.

Over the years the castle was added to and altered but it was never really designed as a particularly defensive location, more a comfortable Royal residence.

The building is occasionally used as a wedding venue.

An angle that shows the quarry on the flank of Dundonald Hill.

At the base of the castle hill is an information centre where castle entry is available for the payment of a small fee.

The castle is run and maintained by volunteers and is open to the public.
