Agencia de Tránsitos Culturales, under the auspices of Galería ATC, operated a physical space in Santa Cruz de Tenerife from 2017 to 2025. Under the leadership of Elle Przybyla and Juan Matos Capote, co-founders of ATC and co-directors of Galería ATC, the gallery maintained a continuous exhibition program and participated in national and international art fairs.

Founded in 2014, Agencia de Tránsitos Culturales began as an independent, non-profit cultural association promoting research initiatives and cultural actions related to the Canarian archipelago. In 2017, the association expanded its activities with the opening of Galería ATC, a white cube gallery space in the heart of Santa Cruz de Tenerife.

Galería ATC presented contemporary art across multiple media, including painting, sculpture, photography, video, and sound art. The gallery's annual program featured both solo and group exhibitions by international and national contemporary artists. As part of its commitment to accessibility, the gallery maintained Flat Files—a collection of works on paper by contemporary artists available for consultation and acquisition by the public, curators, collectors, and art professionals.

Beyond its exhibition space, Galería ATC housed a specialized bookstore offering publications on art, architecture, design, and culture, with proceeds supporting ATC's activities and initiatives.
