Niddry Castle is a substantially restored 15th-century tower house near Broxburn in West Lothian, famous for its connection to Mary, Queen of Scots, who sought refuge here after her escape from Lochleven Castle in May 1568. The impressive L-plan structure rises to four storeys and an attic and was built by Lord Seton around 1500; the Seton family maintained close ties to Mary and provided her sanctuary during her period of captivity. Located approximately two kilometres northeast of Broxburn, this notable fortress reflects the architectural sophistication of late medieval Scottish fortified houses and their role in the nation's turbulent history.
