Arnimplatz, Public square in Prenzlauer Berg, Germany.

Arnimplatz is a public square in the Pankow district of Berlin, with a grassy park area at its center surrounded by residential buildings in the Gründerzeit style. The facades of these buildings show the ornate detailing typical of late 19th-century construction, with multiple stories rising above the square.

The square received its name on 15 September 1903, honouring the poet Achim von Arnim, whose family lived in Berlin. It was created as an open space required by late 19th-century fire-safety building rules. The garden architect Hermann Mächtig designed the 152 by 150 metre layout, which was realised by 1907 with diagonal main paths dividing it into four triangles.

The square is named after the poet Achim von Arnim, and at its center stands a sculpture showing him alongside his wife Bettina, made by sculptor Michael Klein. Visitors can walk right up to the figures and get a close look at this nod to the neighborhood's literary past.

The square is easy to reach by tram and is also a short walk from Schönhauser Allee U-Bahn station. Benches and green patches in the park make it a good spot to stop and rest during a longer walk through the neighborhood.

On the western side of the square stands a transformer station designed by Hans Heinrich Müller, who gave a purely functional piece of infrastructure a carefully considered architectural form. Müller designed many such stations across Berlin, and this one is a rare example of how a utility building can sit naturally in a public green space.
