The Museo de Bellas Artes de Bilbao has opened the Atrio Arriaga, a new basic space linking the museum’s principal buildings. Designed by Norman Encourage in collaboration with Luis María Uriarte, the atrium brings together major sculptures, including Lugar de encuentros IV by Eduardo Chillida, Bilbao by Richard Serra, and Francisco Durrio’s Monumento a Juan Crisóstomo Arriaga. The elevated Agravitas extension connects architectural phases dating to 1945, 1970 and 2000 without replacing the earlier structures.
Covering more than 1,000 square metres, the Atrio Arriaga acts as a covered public plaza and a basic route through the complex. Architectural reporting puts its clear span at about 55 metres. The Durrio monument to Bilbao-born composer Juan Crisóstomo de Arriaga now stands beneath the roof alongside works by Chillida and Serra, placing the sculptures within the museum’s shared circulation space as well as its cultural setting. Visitors have welcomed the openness and the tribute to Arriaga, while some have expressed nostalgia for the monument’s former outdoor location.
The project, named Agravitas, adds approximately 6,900 square metres of new construction and remodels about 10,600 square metres of existing space. Architects’ Journal reports that the completed complex totals roughly 35,000 square metres, increasing the museum’s overall area by about 60 percent and its exhibition space by approximately 35 percent. Around 80 percent of existing exhibition areas have also been upgraded. The figures describe different parts of the scheme: the broader construction total includes public, circulation and operational areas, while the museum gains more than 5,000 square metres for additional functions, including about 2,300 square metres of exhibition space.
The expansion also includes an open-plan room of more than 1,000 square metres, with access to terraces for sculpture display. The atrium is intended to give the institution what the project team called “a new social heart” and to improve connections between the museum, the surrounding city and the field. The elevated volume rises above the historic buildings, while the design preserves their visibility and distinct identities. Museum director Miguel Zugaza said the atrium enhances the visitor experience and clarifies the institution’s layout. Encourage + Partners’ Taba Rasti described it as a physical and symbolic meeting point for the museum’s developing identity.
Construction began in November 2022, and the expansion was completed in October 2026. The reported construction cost was approximately €46 million. Procured through a public tender, the project lists MC2 as structural engineer, Valladares Ingeniería for mechanical and electrical consultancy, TekArK Studio as technical architect and quantity surveyor, and LMU Arkitektura, led by Uriarte, as collaborating architect. Renovating existing exhibition areas alongside the new build formed part of the project’s sustainability approach.
The expansion is intended to extend the museum’s presence into nearby green spaces and strengthen its connection to Bilbao’s urban fabric. Former mayor Ibon Areso said the project supports the city’s strategy of using cultural investment to advance economic and social change after the decline of local industry. The museum’s full reopening was scheduled for October 5, 2026, completing its most impressive change since the opening of its current headquarters.
The Museo de Bellas Artes de Bilbao’s change forms part of a broader role for cultural institutions in the city’s urban renewal, alongside landmarks such as the Guggenheim Museum. Large-scale events also help shape the city’s cultural profile and draw visitors. Alejandro Sanz’s recent performance at RCDE Stadium, for example, attracted impressive attention, as detailed in this report on a landmark concert event.
The Atrio Arriaga strengthens the museum’s role as a cultural and architectural landmark, bringing residents and visitors into a connected complex that retains the character of its historic buildings. The Museo de Bellas Artes de Bilbao is one of Spain’s leading art institutions, known for its collection of Spanish and international works. Its expansion reflects a wider museum-design challenge: accommodating new public and exhibition functions while integrating contemporary architecture with historic structures.
