The Heart of Zaragoza


The Tubo of Zaragoza is a network of narrow streets that houses the main entertainment and tapas area of the city. Next to the mythical singing café El Plata and the very old restaurant Casa Lac, one of the oldest in Spain and Europe dating back to 1825, we find Mains Gallery, a place where art reaches everyone. The art corner of the tube has been running since early 2020 and was born with the idea of bringing art to the daily life of any viewer. Meet a new artist while having a coffee, wait for friends in an outdoor art gallery, which invites us to discover the mysteries of the proposed works! A unique place!
If you are an artist and would like to present your work for a whole month in a different way, this is the place for you!

The exhibition is individual and may share space with another artist as agreed between the artist and the gallery.
