Vatican, of the size of the originals; also the 'Assembly of the Gods,' and the 'Marriage of Cupid and Psyche,' in the Farnesina; the 'Triumph of Bacchus and Ariadne,' from Caracci's picture in the Farnese Palace; and 'Apollo driving the Chariot of the Sun,' from Reni's fresco in the Villa Rospigliosi, at Rome. These celebrated works, and the decoration of the noble apartment, constituted it one of the landmarks of high art in the metropolis. The grand staircase consisted of a centre flight of thirteen moulded vein marble steps, and two flights of sixteen steps, with centre landing twenty-two feet by six feet, two circular plinths, and a handsome and richly-gilt ormolu scroll balustrade, with moulded Spanish mahogany hand-rail. The mansion contained nearly 150 rooms for the private use of the family."[66] The destruction of Northumberland House was due to the necessity of a direct thoroughfare from Charing Cross to the Embankment. As early as 1866, the Metropolitan Board of Works--the predecessor of the London County Council--had perceived the need, and had suggested a new street through the site of Northumberland House and its grounds. "The Duke of Northumberland of that day, however, set his face determinedly against any interference with his ancestral mansion, and his opposition received much support from members of both Houses of Parliament, and from those who looked with disfavour on a proposal to destroy the last of the palaces of the English nobles which three centuries ago stood on the south side of the Strand now occupied by the streets leading from it to the river. The Metropolitan Board was forced to yield to the resistance which then and for several years after was offered to every attempt to get power to take Northumberland House. Eventually the necessities of the case were so strongly pressed that further resistance was abandoned, and the Board having, in 1872, learned that the present Duke of Northumberland was willing to sell his property, an agreement was in the year 1873 concluded and ratified by Parliament, under which the Board acquired his Grace's property upon payment of £500,000, the Board at the same time obtaining power to make the new street."[67] The opposition of the owner of Northumberland House to the destruction of this historical property was natural enough, and many otherwise uninterested persons lamented the proposed demolition. The Duke of Northumberland--the sixth duke of his creation--writing in 1866, said: "The Duke of Northumberland is naturally desirous that this great historical house, commenced by a Howard, continued by a Percy, and completed by a Seymour, which has been the residence of his ancestors for two centuries and a half, should continue to be the residence of his descendants; but the Metropolitan Board of Works are desirous that this house, which, with its garden, is one of the landmarks of London, and is probably the oldest residential house in the metropolis, should be destroyed."
