Oliver Castle

Oliver Castle stands in the Scottish Borders, near the village of Tweedsmuir. It began as a medieval tower house in upper Tweedsdale, part of a line of peel towers along the Tweed Valley. The site includes a prehistoric hillfort on a low knoll about 60 metres above the valley floor. The hillfort covers an area of roughly 60 by 55 metres and has two lines of defence visible as grassy banks. The medieval castle’s exact location remains uncertain, though tradition places it on the hillfort site. Later, a 17th-century house replaced the tower, and in the late 18th century, the present Oliver House was built. The castle’s history is tied to powerful families like the Frasers and the Tweedies. It was originally linked to Clan Fraser, possibly named after Oliver Fraser who gave lands to Newbattle Abbey. Sir Bernard Fraser and Sir Gilbert Fraser held the hereditary office of Sheriff of Tweeddale. Sir Simon Fraser of Oliver fought in the Wars of Scottish Independence but was executed in London in 1306. The estate later passed to the Tweedies after a feud led to the murder of John 2nd Lord Fleming in 1524. Today, the site offers a glimpse of its layered past. The hillfort is protected as a scheduled monument, with visible grassy banks marking its defences. Inside, possible timber house sites and later stone foundations hint at earlier structures. Oliver House, still occupied, stands about 200 metres south-west of the hillfort and incorporates a heraldic panel from the earlier 17th-century house. The old house bears the date 1734 and the initials of James Tweedie of Oliver and his wife Margaret Ewart. Nearby, an older date of 1649 is recorded on the old house, adding to the sense of continuity in this historic place.
