The rehabilitation and extension of the Abade Pedrosa Municipal Museum, a project led by renowned architects Álvaro Siza and Eduardo Souto Moura, is a masterful blend of historical reverence and contemporary innovation. The original museum, housed in the former inn of the São Bento Monastery, is seamlessly connected to a new extension designed to serve as the headquarters of the International Museum of Contemporary Sculpture. This extension is a testament to the vision of the Santo Tirso City Council and sculptor Alberto Carneiro, aiming to celebrate the artistic creations from the International Symposium of Santo Tirso.

Siza and Souto Moura’s design philosophy emphasizes the harmonious coexistence of the old and the new. The connection between the two buildings is both functional and symbolic, allowing each structure to maintain its distinct identity while facilitating a dialogue between them. Siza’s use of marble at the top of the convent corridor contrasts with Souto Moura’s granite door frames, marking a transition that is both tactile and visual. This thoughtful material choice underscores the architects’ commitment to creating a space that respects its historical context while embracing modernity.

The extension’s design is characterized by clean lines and a minimalist aesthetic, reflecting Siza’s belief in the power of simplicity. The building’s interaction with its surroundings is carefully considered, with large windows and open spaces that invite natural light and offer views of the landscape, creating a serene environment for contemplation and appreciation of art. The spatial experience within the museum is designed to guide visitors through a journey of discovery, with each room offering a unique perspective on the sculptures it houses.

Souto Moura describes the project as a “dialogue between materials,” where the interplay of marble and granite not only defines the physical space but also enriches the visitor’s experience. This architectural dialogue is a celebration of both the museum’s historical roots and its forward-looking mission, making it a significant cultural landmark in Santo Tirso.
