The Front State Room

Displays: Portraits and Porcelain

The Front State Room – architecturally restored to its appearance in 1890 with much of the original furnishings returned
This room reveals the opulence of the London town house in the 1870s and sets the scene for visitors to the Wallace Collection. The State Rooms were the grandest rooms in the house, in which the most important visitors were received. When it was the home of Sir Richard and Lady Wallace, visitors to Hertford House first entered the Front State Room, then, as now, hung with portraits. Two items of the modern furniture seen in the room in 1890 were not part of the collection gifted by Lady Wallace and are no longer present, but the mounted porcelain displayed on the cabinets and the chandelier, made by Jean-Jacques Caffiéri in 1571, have been returned to the room.

From The Wallace Collection website:

George IV (1762-1830), Prince Regent 1811-20, and King 1820-30 was a frequent visitor to Hertford House during his his close friendship with the 2nd Marchioness of Hertford (c.1806-20), and he was also a friend of her son, Lord Yarmouth, later 3rd Marquess of Hertford. This portrait, which may have been exhibited at the Royal Academy in 1792, demonstrates Hoppner’s vigorous technique and direct approach to composition. The pose is influenced by the male portraits of Reynolds; indeed Hoppner is known to have copied Reynolds’s earlier portraits of the Prince. The picture has retained its 1810 frame by John Smith, bearing the Prince of Wales’s feathers and motto ‘ich dien’ (I serve).
