Roxburgh Castle is a large 12th century courtyard fortress and was the strongest castle, in the marches. Occupied by both the Scottish and the English through the centuries, it was partly demolished and rebuilt on numerous occasions. Of this impressive Scottish royal castle, only fragments of the gatehouse, curtain wall and flanking towers now remain, with the earthworks of a 16th century English rectangular fort in its centre. With the dense cover of vegetation, it's best accessed in winter. Half a mile north is Floors Castle and 2 miles south is Wallace's Tower.
