Dio Horia in Athens, Greece, is a gallery for contemporary art and culture, founded in 2018 by Marina Vranopoulou. Dio Horia Gallery aims to be a space with Greek roots and international standards, bringing together artists and the general public. A vision along the lines of an 18th century salon, where meeting people and exchanging views is more important than anything else, Dio Horia primarily focuses on young emerging artists from small peripheral countries, promoting the development and exhibition of their work.
