Athens Municipal Gallery, Art museum in Metaxourgeio, Greece.

The Athens Municipal Gallery is an art museum housed in a neoclassical building in the Metaxourgeio neighborhood. It holds a collection of roughly 3,000 works, primarily by Greek artists from the 19th and 20th centuries.

The building was designed in 1833 by Danish architect Hans Christian Hansen as a commercial arcade, but it stood empty from 1835 to 1852. An Austrian firm bought it in 1852 for a steam silk plant that never operated; from 1855 to 1875 the Siriki company ran Greece's largest silk factory here, until cheap Chinese imports ended production. It later served as a barracks, including for ELAS in 1944, and was donated to the city in 1993; the gallery moved in on 27 October 2010.

The neighbourhood is named Metaxourgeio after the silk factory (metaxourgeio means silk mill) that operated in this building from 1855 to 1875, run by the Siriki company; it grew into the largest silk works in Greece and the Balkans before cheap Chinese imports ended production. The gallery's collection was founded in 1923, and its first director was Stavros Papapanagiotou; Spyros Papaloukas led it from the 1940s until his death in 1957.

The gallery occupies two buildings on Avdi Square, covering 1,500 m², so allow time to move between them. It is closed on Mondays; on other days it opens mornings and again in the evening, with Sunday mornings only. Admission is free, and the gallery can be reached on foot from Metaxourgeio station.

The gallery's collection was formally established in 1923, when the first artworks were purchased; its first director was Stavros Papapanagiotou, and Spyros Papaloukas led it from the 1940s until his death in 1957. The 19th century is thinly represented, while the 1930s and 1940s carry great weight, alongside contemporary artists such as Chronis Botsoglou and Makis Theofylaktopoulos.
