Arnswalder Platz, Public square in Prenzlauer Berg, Germany.

Arnswalder Platz is a rectangular public square in the Pankow district of Berlin, with green areas, play zones, and a central fountain. It is listed as a cultural heritage monument, which gives it a protected status within the neighborhood.

The square was marked in the 1862 Hobrecht Plan as Area A and was given its current name in 1902 after a Pomeranian town called Arnswalde, today known as Choszczno in Poland. The name reflected the ties that Berlin then held with eastern regions of the German territory.

The square's name refers to Arnswalde, now Choszczno in Poland, a town in the former Province of Pomerania. The fountain, carved from red Rochlitz porphyry tuff, shows a reaper with sheaves and a fisherman with a net on the northeast side, and a shepherd with a ram and a mother with child on the northwest side.

The square is open at all times and works well for a walk, some play, or a break in a green setting. The activity areas and seating around the fountain are best enjoyed in dry weather.

The fountain's design was not made for this square: Hugo Lederer created it for a 1910 competition for a monumental fountain in Buenos Aires, where it won fourth prize and was never built. Berlin bought the project in 1927, and the 300 m³ of carved Rochlitz porphyry tuff arrived in 1934.
