Floors Castle

Floors Castle: Scotland's Largest Inhabited Castle, Above the River Tweed

When the 1st Duke of Roxburghe needed a new house in 1721, he turned to William Adam — the architect who would later father Robert Adam and establish the most celebrated architectural dynasty in 18th-century Britain. The result was Floors Castle: a Georgian country house of considerable scale, set on a natural terrace above the River Tweed, with views south to the ruins of Roxburgh Castle where King James II was killed by an exploding cannon in 1460.

In the 19th century, William Playfair added turrets, battlements and crenellations, transforming the restrained Georgian composition into the romantic, turreted castle that greets visitors today. It is, by area, the largest inhabited castle in Scotland.

The Innes-Ker family — Dukes of Roxburghe — have lived at Floors since its completion. The estate extends across 21,000 hectares of the Scottish Borders, including woodland, riverside walks and the Victorian Walled Gardens that are among the most celebrated in the region. The castle opened to the public in 1977 and remains a private family home. This guide covers everything you need to plan your visit.

Where Is Floors Castle?

Floors Castle is on the outskirts of Kelso, in the Scottish Borders, just off the A699. From Edinburgh, allow around one and a quarter hours via the A68 towards Jedburgh, then signs for Kelso. From Berwick-upon-Tweed, take the A698 north; allow around 30 minutes. From Kelso town centre, the castle is a 15-minute walk or a very short drive.

Free parking is available on site. The nearest railway station is Berwick-upon-Tweed, approximately 30 minutes away, with bus connections to Kelso.

A Brief History of Floors Castle

The land at Kelso has a long connection with the Ker family. Before the Reformation, the site was owned by the monks of Kelso Abbey; after the Reformation, King James VI granted the lands to Robert Ker, who became the 1st Earl of Roxburghe.

His descendant John Ker played a pivotal role in one of the most consequential events in British history: he was the Secretary of State for Scotland who worked to bring about the Acts of Union of 1707, which united the Kingdom of Scotland with the Kingdom of England. For this he was elevated to Duke of Roxburghe, and it was his grandson John, 1st Duke, who commissioned William Adam to design the new castle between 1721 and 1726.

Adam's original building was a substantial but relatively restrained Georgian house. In the 19th century, the Edinburgh architect William Playfair — responsible for some of Edinburgh's most celebrated neoclassical buildings — was commissioned to transform Floors into something more romantically Scottish. His additions of turrets, battlements and crenellations gave the castle its present fairytale silhouette and unified the various elements of the building into a coherent Gothic Revival composition.

The Roxburghe family's most historically significant neighbour is visible from the castle grounds: the ruins of Roxburgh Castle across the River Tweed, site of James II's death in 1460 when a cannon exploded beside him during the siege — a death that has been called the most ironically Scottish in history.

The remarkable thing about Floors is its scale. Scotland has many grand houses and many castles, but at 21,000 hectares and with a principal building of this size, Floors represents an ambition of estate ownership that belongs to a different category.

Architecture & Design

William Adam's original Floors was Georgian in character — symmetrical, proportioned, built of warm sandstone that catches the light on the natural terrace above the Tweed. The orientation takes advantage of the river view and the ruin of Roxburgh Castle in the middle distance: the landscape is part of the composition, as it was in all of Adam's greatest work.

Playfair's 19th-century additions gave the building its current character: turrets and battlements along the roofline, pepper-pot towers at the corners, crenellations along the parapets — all executed in a sympathetic continuation of Adam's sandstone, giving the castle its unified, romantic profile.

Inside, the principal rooms display the fine art, porcelain and furniture accumulated by the Roxburghe family across three centuries: large windows, ornate ceilings and period decoration throughout the main reception rooms. The Victorian Walled Gardens, separately enclosed on the estate, contain glasshouses, herbaceous borders and the formal Millennium Garden — one of the more complete Victorian walled garden survivals in the Scottish Borders.

Legends & Lore

Floors Castle itself has no established ghost tradition, but the landscape it commands carries real historical drama. From the castle grounds, across the River Tweed, the turf mound of Roxburgh Castle is visible — one of the four great medieval Scottish burghs (alongside Edinburgh, Stirling and Berwick) that was so completely demolished after its final capture that almost nothing remains above ground.

Here, in August 1460, King James II of Scotland was standing beside a cannon when it exploded, killing him. He was 29. The cannon was probably his own. The siege continued, and his widow — Mary of Guelders — oversaw its completion, but the castle was demolished to prevent future English occupation. The most powerful fortress in the medieval Scottish Borders is now a grass-covered mound.

The Scottish Borders as a whole is a landscape richly layered with the history of the Anglo-Scottish borderlands: the reivers who raided across both sides of the frontier for centuries, the abbeys that were repeatedly attacked by English armies, the tower houses built by every family of any means. Floors sits at the heart of this landscape, and exploring it gives access to some of the finest medieval and historic heritage in southern Scotland.

Visiting the Castle

Floors Castle opens seasonally from spring to late summer, generally from April through September. The visit takes in the principal rooms of the castle — the fine art collection, the family portraits, the period furniture and the ornate ceilings — with guided tours available subject to availability. Check the official website for current tour arrangements.

The Victorian Walled Gardens are a highlight for garden enthusiasts and are accessible seasonally as part of the main ticket or on an annual pass basis. The woodland and riverside walks on the 21,000-hectare estate are an exceptional outdoor complement to the castle visit, and a cycle trail is also available. The Terrace Café provides refreshments including tea and cake; the Apple Shed gift shop and deli sells local produce and souvenirs.

Where to Stay Near Floors Castle

Floors Castle does not offer visitor accommodation. The town of Kelso, a 15-minute walk, has a range of hotels, guesthouses and bed and breakfasts, and the town itself — with its cobblestone streets, fine Georgian architecture and abbey ruins — is an enjoyable base for exploring the Scottish Borders. Melrose, around 20 miles west, is another excellent base for the wider region.

Conclusion

Floors Castle is Scotland's largest inhabited castle, designed by William Adam in 1721 and transformed into its present romantic silhouette by William Playfair a century later, on a terrace above the River Tweed in the Scottish Borders. Across the river, the mound where James II died in 1460 is still visible.

The Victorian Walled Gardens are some of the finest in the Borders. The estate's 21,000 hectares of woodland and riverside offer walking that few castle visits in Scotland can match. And the Innes-Ker family — Dukes of Roxburghe — have been here since the first stone was laid, which means Floors is, as all the best castles are, still a home.
