Nitra gallery is a continuation of Atrion gallery, founded in Thessaloniki in 1994. In 2013, the baton was passed to Aliki Tsirliagkou and to the next generation, as Atrion became Nitra, based in the city’s roman agora neighborhood. In 2017 Nitra expanded by opening a new gallery space in downtown Athens, in Kolonaki.

Nitra presents a dynamic, multifaceted contemporary art exhibition program, representing both Greek and international artists with a range of practices, from pure painting to applied Arts. Professional experience with the Greek contemporary art world, an overall conception of artistic production in Greece over the past three decades as seen through two generations, and the strong ties Nitra has developed with the city of Istanbul have all led to the the creation of an international network of artists, collectors and professionals in the field.
