My next visit of the day was to Drummond Castle Gardens. These were used in series 2 as the gardens at Versailles.
Drummond has all the characteristics of a courtly, 17th century Scottish Renaissance garden. It is a composite garden, restructured in early Victorian times and renewed again in the 20th century when the garden framework and the exceptional interest of the original 19th century design were carefully preserved.

The gardens are open to the public from May to October but the castle is not open to the public. Amazing gardens worth a wander around especially on a lovely warm day.
