Bowhill, home to the Duke and Duchess of Buccleuch and Queensberry

The interiors of Bowhill in the Scottish Borders, one of the seats of the Duke and Duchess of Buccleuch and Queensberry, have a rich and colourful history, along with one of the most impressive private art collections in the country

The house saw another burst of expansion in the 1830s for the 5th Duke, when Scottish architect William Burn lengthened the Regency house in both directions in the existing simple classical style and local grey whinstone. His centrepiece was a double-height, galleried saloon. A master planner, Burn was attuned to every requirement of his grand Victorian clients with their crowd of children - the Buccleuchs had seven - and army of servants. His new family apartment, consisting of the ducal bedrooms and nurseries connected by a spiral staircase, contains at its heart the duchess's boudoir, a glittering casket of a room, lined with old Chinese wallpaper and laden with silks, fringes and needlepoint in an exquisite fusion of form and purpose. 'This was my mother's domain,' says Richard. 'It always was a sanctuary; a peaceful, private place. It remains one of the most complete rooms in the house, with all its original furnishings in place, down to the hearthrug.'

The transformation of the interiors of Bowhill reflected the upheav­als of the twentieth century. 'There are no photographs of pre-1920 interiors as the house didn't merit it,' says Richard. All this changed with the arrival of treasures from Montagu House and Dalkeith, as not only had the Buccleuchs themselves collected, but they had also married into great collections, notably that of the dukes of Montagu. As a result, the country retreat with its large, well-proportioned rooms became home to a stream of French marquetry furniture, including many pieces with royal provenance; British portraits by Reynolds, Gainsborough, Lawrence and their peers; Mortlake tapestries woven from Mantegna's cartoons; old masters, including one of Canaletto's most iconic London scenes; and troves of silver, miniatures and Sevres porcelain.

Since inheriting, Richard has been quietly reordering some of the collections at Bowhill. He has created a 'museum quarter' out of three adjacent rooms to display the Walter Scott collection, the portrait minia­tures - which are second only to those in the Royal Collection - and the belongings of his royal ancestor, the Duke of Monmouth, illegitimate son of Charles II, who married Scott heiress the Countess of Buccleuch. Their union in 1663 signalled the creation of the Dukedom of Buccleuch.

Elsewhere, the staggering collection continues to serve as a backdrop to life at Bowhill - nowhere more so than in the dining room, which is hung with the pick of the portraits and the Canaletto. 'There's a tremendous history of feasts,' says Richard. 'The painter David Wilkie described scenes of never-ending toasts and songs sung till the small hours. Even today we get out all the silver for festive occasions, continuing the tradition of joyful living at Bowhill.'
