Lancaster House, St James's, London: lateral view of the entrance portico with St James's Palace in the background

NOTES: Construction on Lancaster House, the last great Georgian London mansion, began in 1825 for the Duke of York and Albany, the second son of King George III and was initially known as York House. The exterior was designed by Benjamin Dean Wyatt and was only a shell at the Duke's death in 1827. The house was purchased by the 2nd Marquess of Stafford in 1829 and the interiors were completed by Wyatt, Sir Charles Barry and Sir Robert Smirke by 1840.
