White Hall was at one time the largest palace in Europe, with more than 1,500 rooms, overtaking the Vatican, before itself being overtaken by the expanding Palace of Versailles, which was to reach 2,400 rooms. The palace gives its name, Whitehall, to the street located on the site on which many of the current administrative buildings of the present-day British government are situated, and hence metonymically to the central government itself. At its most expansive, the palace extended over much of the area bordered by Northumberland Avenue in the north; to Downing Street and nearly to Derby Gate in the south; and from roughly the elevations of the current buildings facing Horse Guards Road in the west, to the then banks of the River Thames in the east (the construction of Victoria Embankment has since reclaimed more land from the Thames)—a total of about . It was about from Westminster Abbey.
