Rosyth Castle is a fifteenth-century ruined tower house on the perimeter of Rosyth Naval Dockyard, Fife, Scotland.
It originally stood on a small island in the Firth of Forth accessible only at low tide, and dates from around 1450, built as a secure residence by Sir David Stewart, who had been granted the Barony of Rosyth in 1428.
The original tower house was enlarged and extended in the 16th and early 17th centuries.
