Wallace Collection Wallace Collection The Wallace Collection is an art collection in London open to the public, housed at Hertford House in Manchester Square, the former townhouse of the Seymour family, Marquesses of Hertford. It comprises an extensive collection of fine and decorative arts from the 15th to the 19th centuries with important holdings of French 18th-century paintings, furniture, arms and armour, porcelain and Old Master paintings arranged into 30 galleries. It was established in 1897 from the private collection mainly created by Richard Seymour-Conway, 4th Marquess of Hertford (1800–1870), who left both it and the house to his illegitimate son Sir
Marquess of Donegall and on his death in 1883 the barony of 1841 became extinct. He was succeeded in his other titles by his younger brother, the fourth Marquess. On the death of his grandson, the sixth Marquess, in 1975, the line of the second Marquess failed. The late Marquess was succeeded by his kinsman the fifth Baron Templemore (see below), who became the seventh Marquess. From 1975 until 1999, when most hereditary seats were abolished with the passage of the House of Lords Act 1999, the Marquess sat in the House of Lords as "Baron Fisherwick" in the Peerage of Great Britain.
