Northumberland Avenue in the context of "Thames Embankment"

The Palace of Whitehall – also spelled White Hall – at Westminster was the main residence of the English monarchs from 1530 until 1698, when most of its structures, with the notable exception of Inigo Jones's Banqueting House of 1622, were destroyed by fire. Henry VIII moved the royal residence to Whitehall after the old royal apartments at the nearby Palace of Westminster were themselves destroyed by fire. Although the Whitehall palace has not survived, the area where it was located is still called Whitehall and has remained a centre of the British government.

Whitehall was at one time the largest palace in Europe, with more than 1,500 rooms, before itself being overtaken by the expanding Palace of Versailles, which was to reach 2,400 rooms. 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 23 acres (9.3 ha). It was about 710 yards (650 m) from Westminster Abbey.

Charing Cross (/ˈtʃærɪŋ/ CHARR-ing) is a junction in Westminster, London, England, where six routes meet. Since the early 19th century, Charing Cross has been the notional "centre of London" and became the point from which distances from London are measured. Clockwise from north, the routes that meet at Charing Cross are: the east side of Trafalgar Square leading to St Martin's Place and then Charing Cross Road; the Strand leading to the City; Northumberland Avenue leading to the Thames Embankment; Whitehall leading to Parliament Square; The Mall leading to Admiralty Arch and Buckingham Palace; and two short roads leading to Pall Mall and St James's.

Historically, the name was derived from the hamlet of Charing ('Riverbend') that occupied the area of this important road junction in the middle ages, together with the grand Eleanor cross that once marked the site. The medieval monumental cross, the Charing Cross (1294–1647), was the largest and most ornate instance of a chain of medieval Eleanor crosses running from Lincoln to this location. It was a landmark for many centuries of the hamlet of Charing, Westminster, which later gave way to government property; a little of the Strand; and Trafalgar Square. The cross in its historical forms has lent its name to its locality, including Charing Cross Station. On the forecourt of this terminus station stands the ornate Queen Eleanor Memorial Cross, a taller emulation of the original, built to mark the station's opening in 1864.

The Playhouse Theatre is a West End theatre in the City of Westminster, located in Northumberland Avenue, near Trafalgar Square, central London. The Theatre was built by F. H. Fowler and Hill with a seating capacity of 1,200. It was rebuilt in 1907 and still retains its original substage machinery. As of November 2021, the theatre has been refurbished and advertised as the Kit Kat Club while it is hosting a revival of the musical Cabaret.
