History

The estate was once owned by the Earls of Moray and then the Earls of Dunbar before passing to the Sinclair family. A castle may have existed at the site prior to the current mansion house.
Robert Sinclair of Longformacus built the current mansion house in the early 18th century. A plaque shows the inscription "Adam delin" by the Scottish architect William Adam.
