The H2O Gallery opened in October 1989 with the exhibition of architectural drawings by the then young Dutch architect Ben van Berkel. In 1991, the gallery started reissuing pieces of historical design by recovering the furniture created by the architect F. J. Barba Corsini in 1995 for the penthouses in Gaudí's La Pedrera.
The H2O Gallery organises a wide variety of architecture, design, photography and contemporary art exhibitions.
