Alte Synagoge, Former synagogue in Hagenow, Germany.

The Alte Synagoge in Hagenow is a restored building consisting of the main synagogue and a front house structure. The complex included residential quarters, a religious school, and a ritual bath for community use.

A prayer room stood on the site by 1781; in 1820 community leader Hirsch Samuel Meinungen bought a garden on Hagenstraße for 100 Reichstaler, and the timber-framed complex was completed in 1828. The Israelitische Gemeinde zu Hagenow inaugurated the synagogue on 15 August 1828. The last service was held in 1907. During the November Pogroms of 1938 the interior was devastated but the building was not set on fire because of nearby structures; in 1942 the complex was forcibly sold.

The building recalls the Jewish community that once lived and worshipped here. Today visitors find exhibitions inside that show how Jewish life looked in the city and the surrounding region.

The complex is entered from Hagenstraße, where the front house with the school and community rooms stands; the synagogue itself lies in the rear courtyard, reached through the passage. The mikveh, a groundwater-fed bath with an oak-plank barrel sunk into the floor, is preserved inside. The site belongs to the Hagenow local museum, so access to the exhibition rooms and the synagogue follows the museum's opening arrangements.

During the restoration, old paint layers were uncovered on the front wall of the prayer room, and the outline of the destroyed Torah ark can still be made out there. The building was not set on fire during the November 1938 pogroms because of its closeness to neighbouring houses.
