After the Restoration of the English monarchy in 1660, Piccadilly and the area to the north (Mayfair) began to be systematically developed as a fashionable residential locality. Some of the grandest mansions in London were built on the northern side of Piccadilly: Clarendon House, Berkeley House (later Devonshire House), and Sir John Denham's house (later Burlington House) were built in the 17th century. Later mansions included Melbourne House (now The Albany), Apsley House, Bath House and Cambridge House. Several members of the Rothschild family had mansions at the western end of the street, and that part was colloquially referred to as Rothschild Row.
