Statement of Special Interest
Originally an earlier L-plan tower house, Oxenfoord Castle was altered and extended by a number of generations. The most significant changes took place when the estate passed into the hands of Sir John Dalrymple and Lady Elizabeth, his cousin who had married against the wishes of her father. She had inherited the property on his death and, together with her husband, commissioned Robert Adam (with whom her husband had studied at University) to prepare a scheme for restoration and extension. These plans are housed at the Soane Museum. The Adams had recently converted Culzean Castle from an L-shaped house into a perfect rectangle with lower wings and flanking towers. Much the same was proposed at Oxenfoord, although the wings were slightly reduced in scale. At about this time the bridge (listed separately) was added to the castle. Designed by Alexander Stevens, (the bridge builder and architect with whom Adam had worked before, see Ayr Bridge), it borrows forms from the house. Later, a new church and burial ground was constructed to replace the old ones still found within the policies. This was due to it being sited too near to the newly refurbished castle and they were paid for fully by the Dalrymples (The Callanders of Prestonhall later moved the manse for much the same reason). By the time their son took over the property in the early 1800's, new ideas about country house design were well advanced. William Burn was called upon by the eighth Earl of Stair to further improve the castle. The symmetrical facade was added to by means of a lower wing culminating in a new complex entrance. Burn copied Adam's earlier style, reusing the pepper-pot turrets, machicolated cornice and string courses. He also added the segmental bay windows to the E and N elevations. The building stayed in the ownership of the Dalrymple family, with Lady Marjorie Dalrymple establishing a school in it in 1931. Until 1993, Oxenfoord Castle School was housed here. The castle has now reverted back into private use and is at the centre of the Oxenfoord estate.
