Pappelplatz, Garden monument and historical square in Berlin-Mitte, Germany.

Pappelplatz is a triangular square north of Invalidenstraße, between Ackerstraße and Elisabethkirchstraße, in Berlin-Mitte. Its centre holds the Geldzählerbrunnen, a fountain with Ernst Wenck's over-life-size kneeling athlete in a money-counting pose, carved from shell limestone and unveiled in 1912. A semicircular three-step stair on the north side leads up to a broad plateau with benches, and dense planting screens the surrounding streets.

Pappelplatz was laid out in 1833 as a triangular marketplace north of Invalidenstraße, serving the residents of a new housing complex between Ackerstraße and Elisabethkirchstraße. In 1892–93, city garden director Hermann Mächtig gave it its first green space, a simple design with a semicircular seating niche, while keeping a strip along Invalidenstraße for weekly markets. The square is listed as a garden monument, and after 1990 it was restored with historic materials, completed in 2006.

The square's name comes from the poplars growing on it. Since 1912 its centre has held Ernst Wenck's shell-limestone sculpture of a kneeling athlete in a money-counter's pose, meant to recall the weekly markets once held here. The broad strip along Invalidenstraße was kept for those market days.

The location is directly accessible via a tram stop, which simplifies arrival from different parts of Berlin. The open structure with multiple pathways allows visitors to explore the square easily and navigate the grounds.

The 1912 sculpture by Ernst Wenck, carved from shell limestone, depicts a kneeling athlete in the pose of a money counter. It was chosen from 53 designs submitted by 43 artists in a 1907 competition and recalls the square's former market days.
