Neidpath Castle is an L-plan rubble-built tower house, overlooking the River Tweed about 1 mile (1.6 km) west of Peebles in the Borders of Scotland.

[2] Sir William de Haya (d.c.1390) probably built the present castle in the late 14th century.

[1] James Taylor, writing in 1887, states that the 13th-century tower was demolished by artillery during the siege[3] and the Listed building report notes that there was damage to the west wing.

The 3rd Earl inherited the title and estates of the Duke of Queensberry in 1778, and subsequently let Neidpath to tenants.

"[1][6] On the death of the Duke in 1810, the castle, along with the earldom of March, was inherited by the Earl of Wemyss, although the dukedom went to the Scotts of Buccleuch.

Other features include a pit dungeon, and some small exhibitions of artifacts found in the locale.

Originally serving as ornate garden terraces these were apparently enclosed by a wall which was recorded in 1581 and listed as a "sloping parterre" in 1815.

Forbidden to marry the son of the laird of Tushielaw, who was considered below her station, she dwined while her lover was sent away.
