Inverugie Castle near Peterhead in Aberdeenshire is a scheduled monument preserving the ruins of a motte-and-bailey fortress and Renaissance chateau built by the Cheyne family in the 12th century. Located on the banks of the River Ugie, the castle once featured a four-storey block with circular angle towers and a stair turret in a splendid double-courtyard design. Following the Jacobite Rebellion, the property passed to the Ferguson family, but deteriorated after 1820. Gales in 1890 caused significant collapse, though the site today remains a poignant reminder of Aberdeenshire's medieval heritage and architectural ambitions.
