Platz der Republik, public square in Berlin, Germany

Platz der Republik is a flat, grassy square of about 36,900 square metres directly west of the Reichstag building. Its lawn is edged with low hedges and a few trees, and the Reichstag's pale stone facade, six-column portico, triangular pediment and glass dome rise behind it. The square is open and unbuilt, with no water features.

The square began around 1730 as a parade ground outside the Brandenburg Gate and was renamed Königsplatz on 18 December 1864. The Reichstag building replaced Count Atanazy Raczyński's palace between 1884 and 1894, and the Victory Column stood at the centre from 1873 until its removal in 1938–39. The square first took the name Platz der Republik in 1926, was renamed back to Königsplatz by the Nazis in 1933, and received its current name again in 1948.

The name Platz der Republik was first used from 1926 to 1933 to mark the abolition of the monarchy, was dropped under the Nazis, and returned in 1948. The square's best-known gathering came on 9 September 1948, when 300,000 Berliners protested the blockade and Ernst Reuter gave his "Ihr Völker der Welt" speech. A policeman shot the 15-year-old pupil Wolfgang Scheunemann near the Brandenburg Gate during that protest.

The square is easily accessible by public transportation and features wide, flat pathways for walking along with open grassy areas for sitting and relaxing. The best time to visit is during warmer weather or when events are scheduled, as the space becomes more lively then.

The 6 by 10 metre federal flag raised here at midnight on 2–3 October 1990, flown day and night and lit after dark, is probably the largest German flag. In April 2006 Adidas asphalted part of the lawn for a miniature Olympiastadion with about 8,000 seats showing World Cup matches, then restored the surface and replaced removed trees with matching ones found across Germany.
