Mutterturm, Gothic Revival tower in Landsberg am Lech, Germany.

The Mutterturm is a 30-metre tower in a small park on the west bank of the Lech in Landsberg am Lech. Built of tuff blocks, it is divided into five storeys and has an asymmetrical outline. It once housed a memorial room for Herkomer's mother and father as well as his studio.

Hubert von Herkomer had the tower built in memory of his mother, who died at Christmas 1879 after the family returned from England to Landsberg in 1877. He bought the plot next to his parents' house in 1880 and erected the 30-metre tower to his own design; work stretched to about 1887 for reasons of cost. On 2 September 1888 he married his third wife, Margaret Griffiths, inside it.

Hubert von Herkomer built the tower in memory of his mother, who died at Christmas 1879 after the family returned from England to Landsberg. The tower held a memorial room for her, and later for his father, alongside his studio. In 1888 he married his third wife, Margaret Griffiths, inside the Mutterturm itself.

The tower stands in a small park on the west bank of the Lech, and the original residential building next to it, linked to the tower by an enclosed, roofed wooden bridge, houses the Herkomer Museum with around 100 exhibits as well as a registry office. Approach from the river side to see the tower and bridge together.

The tower is a 30-metre tuff-block structure split into five storeys, built to Herkomer's own design; work began in 1880 and dragged on until about 1887 for cost reasons. Inside, an honour room for his mother and later his father sat alongside space for his studio. A covered wooden bridge links it to the former family house, which has held the Herkomer Museum since 1990.
