Open House Porto is a celebrated architectural event that invites the public to explore the evolving narratives of buildings in Maia, Matosinhos, Porto, and Gondomar. The 11th edition, themed Pentimenti, takes place on July 4-5, 2026, under the insightful curation of architect Maria Souto de Moura and photographer Francisco Ascensão. This year's theme draws inspiration from the layers and transformations found in both art and architecture, allowing participants to discover over fifty unique structures that showcase significant historical value and innovative re-purposing.

Visitors can engage in free guided tours, discussions, and educational activities designed for all demographics. Notable buildings, some opening their doors for the first time, provide a rich tapestry of stories reflecting sustainability and adaptation. Open House Porto thrives on community involvement, with around 400 volunteers and collaborations with experts, enhancing the celebration of architecture and its role in shaping urban identity. Join this vibrant exploration and experience the hidden stories that architecture can tell.
