Neidpath Castle is a fourteenth-century Scottish castle commanding a picturesque position on a rock cliff above the River Tweed near Peebles in the Scottish Borders. Built by Sir William Hay in the late 1300s following his marriage that brought the barony into the Hay family, the castle hosted notable guests including Mary Queen of Scots in 1563 and later her son James VI. The castle resisted Cromwell's army longer than any other stronghold south of the Forth in 1650, though cannon damage eventually forced surrender. Following financial difficulties, it passed to the Douglas Duke of Queensberry in 1686. Today it operates as both a wedding venue and self-catering accommodation, offering pre-booked tours and private events in this historically significant location.
