Founded in 2014 by Andrei Breahnă (gallerist and cultural manager) and Raluca Șoaita (architect), Gaep was initially named Eastwards Prospectus and focused on artistic practices from Eastern Europe. In 2019, the gallery changed its name to become consistent with the new international nature of the programme, a result of the connections established over time with the international milieu of contemporary art. The current programme includes artistic practices that reflect various sociopolitical contexts and different generational positions, in an attempt to transcend established borders and circulate artworks and ideas in new ways.

In the span of six years, between 2014 and 2020, the gallery presented almost 30 exhibitions, showcasing new artworks and introducing international artists to Romanian audiences, and participated in more than 20 international art fairs. Two of these participations have been award-winning: Opening Prize at ARCOmadrid 2019, with a solo presentation of Ištvan Išt Huzjan, and Sardi per l’arte Back to the Future Special Mention at Artissima 2017, with a solo presentation of Marilena Preda Sânc.
