Ashburnham Place is an English country house, now used as a Christian conference and prayer centre, five miles west of Battle, Sussex. It was one of the finest houses in the southeast of England in its heyday, but much of the structure was demolished in 1959, and only a drastically reduced part of the building now remains standing.
The village of Ashburnham was the home of the Ashburnham family from the 12th century. The family became wealthy through their land holdings in Sussex and around Pembrey in Carmarthenshire, and later from their participation in the Wealden iron industry. Only the cellars remain from the earliest known house on the site, dating from the 15th century. This house was abandoned in the 16th century and confiscated by Queen Elizabeth I. The Ashburnham family recovered their estate under Charles I, and John Ashburnham was a loyal servant of the King. He was forced to sell the estate to the Relf family in the English Commonwealth, to pay fines levied for supporting the King. John Ashburnham recovered the estate again after the English Restoration. His grandson and namesake, John Ashburnham, was created first Baron Ashburnham in 1689. The house was largely rebuilt to designs of the neo-Palladian architect Stephen Wright and the local direction of the builder John Morris of Lewes, ca 1757-61.
The park, covering some 200 acres (0.81 km2) and including three large lakes around the house, was laid out by the landscape architect Capability Brown in the mid-18th century. Brown's orangery, c. 1767, houses the oldest camellia in England. Brick external additions were made to the house in Gothic Revival style in 1813-17, by a third John Ashburnham, the second earl of Ashburnham, to designs by George Dance the Younger. Robert Adam designed entrance lodges for the second Earl in 1785.George Ashburnham, 3rd Earl of Ashburnham, commissioned architectural drawings from John Soane, but it is not known if the suggested additions, including a porte-cochere, were built. The house was refaced in stone in the early 19th century, and then, when fashions changed, a second, red brick outer skin was added in 1853.
