Bilbao Fine Arts Museum’s Agravitas Opens October 6

Bilbao Fine Arts Museum presented its completed Agravitas expansion on October 2 and will open the transformed complex to the public on October 6. The intervention is significant not simply because it enlarges the museum, but because it redistributes a collection spanning antiquity to the present across three distinct generations of architecture.

 
 

The Public Opening Is October 6, Not October 5

The press presentation took place on Friday, October 2, 2026. An institutional reopening ceremony is scheduled for Monday, October 5, the museum’s 118th anniversary; general visitors enter the following day, Tuesday, October 6.

That sequence resolves an apparent discrepancy in the first reports. EFE and RTVE both used October 5 in descriptions of the “reopening,” while their reporting also identified October 6 as the day the public would enter. A final-day account from Radio Bilbao states the distinction directly: ceremony on October 5, public opening on October 6.

The project, designed by Foster + Partners with Bilbao architect Luis María Uriarte, follows almost four years of work that began in November 2022. The museum never remained wholly shut for that entire period; it shifted public activity between available areas as construction advanced. What opens on October 6 is therefore the completed ensemble, not the return of an institution that had been continuously closed.

Why the Expansion Has Three Different Area Figures

The museum’s 2025 plan lists 6,743 square meters of new construction, opening reports describe about 6,000 square meters of new construction, and the 2,300-square-meter figure refers to exhibition space. The museum’s 2025 action plan gives the formal project scope as 6,743 square meters of new construction plus remodeling of 8,000 square meters already in the complex. Opening-day reports describe the addition as about 6,000 square meters, while the museum’s 2025 plan lists 6,743 square meters of new construction; no published reconciliation explains the difference.

The 2,300-square-meter figure is narrower: it is the final reported amount of versatile exhibition space within Agravitas, distributed over two levels. The 2,300 square meters covers indoor exhibition space across Agravitas’s two levels; the 700-square-meter sculpture terrace is reported separately. The museum’s earlier plan paired a 1,500-square-meter temporary gallery with a 700-square-meter terrace, totaling 2,200 square meters for that particular gallery-and-terrace package.

An April 2025 Basque Government notice used still another formulation: 5,000 additional square meters and 2,250 remodeled. It was an interim announcement tied to an earlier June 2026 opening target. It does not define the narrower scope behind those figures, so it should not replace the museum’s more detailed project schedule or the completed building’s reported program.

A 55-Meter Span, Not a Museum 55 Meters High

Agravitas places a ribbed white volume above the 1945 and 1970 buildings, supported by large V-shaped columns. This is where two early accounts introduced a consequential unit error. El País described the bridge as passing 55 meters above the older buildings, and RTVE similarly called it 55 meters high. The final technical description identifies 55 meters as the bridge’s span and places the roof at 11 meters.

That distinction changes the reader’s mental picture. The architects have not placed a gallery at skyscraper height. They have made a long-span structure cross above protected buildings with relatively few supports, leaving the earlier architecture legible below. It turns the broader question of whether architecture is art into a practical museum problem: how to gain large galleries without erasing the rooms and facades that already carry the institution’s history.

Beneath the new structure, the roughly 1,000-square-meter Atrio Arriaga encloses the former outdoor plaza around Francisco Durrio’s monument to composer Juan Crisóstomo de Arriaga. It now brings that fountain-sculpture into conversation with works by Eduardo Chillida, Richard Serra, Pablo Palazuelo, and Cristina Iglesias while connecting the museum’s entrances and circulation routes.

How the Three Buildings Divide the Art

The original museum building, designed by Fernando Urrutia and Gonzalo Cárdenas, opened in 1945 after the city’s fine-arts and modern-art museums were merged. Its reinstated historic entrance now leads into the older portion of the collection, whose chronological sequence reaches the early decades of the 20th century.

The 1970 extension by Álvaro Líbano and Ricardo Beascoa was conceived for contemporary art. Its renovated galleries now carry the story from modernism to the present. A 2001 intervention by Uriarte had already improved links between the two buildings; Agravitas adds a shared atrium, vertical circulation, and new upper levels rather than treating either predecessor as disposable.

The museum describes Bildu(e)mak as a selection of close to 1,000 works, although Naiz reports nearly 650 works across its 43 rooms. Works by women are deliberately inserted throughout the chronology, from Sofonisba Anguissola among Renaissance painters to Idoia Montón near the contemporary end. This curatorial structure matters as much as the added floor area: the museum is using the reopening to revise who appears inside an otherwise chronological account.

Agravitas itself takes on functions the older rooms could not easily provide. Its upper hall can accept large temporary projects, its lower level establishes Design and Architecture as a collection category, and its terrace creates an outdoor setting for sculpture. The inaugural program also foregrounds collecting: La búsqueda del comienzo presents more than 100 works associated with Plácido Arango, while Visiones de ultramar draws on Patricia Phelps de Cisneros’s collection of art from the Americas.

What Visitors Can See From October 6

The museum plans an open-house period from October 6 through October 13. EFE reports that standard admission will then be €12, with a €6 reduced ticket and free access to the collection on Tuesdays; a joint ticket with the Guggenheim Museum Bilbao is due to begin October 14. Those terms should be checked against the museum’s visitor page before traveling because its construction-period information was still visible shortly before reopening.

The most consequential change is available without reducing the project to a new facade: visitors can follow one continuous sequence from antiquity through contemporary art, then move into spaces designed for large temporary exhibitions, design, education, and sculpture.

 
 

What the Completed Agravitas Establishes

The dated sequence is now clear: press presentation on October 2, institutional ceremony on October 5, and public opening on October 6. The museum’s formal plan establishes 6,743 square meters of new construction and 8,000 square meters of remodeling; the widely reported 2,300 square meters refers only to exhibition space in the new wing. The 55-meter measurement is the bridge span, not its height, and the final technical account places the roof at 11 meters.

The collection is also newly legible as two chronological runs through the 1945 and 1970 buildings, with Agravitas providing temporary, design, educational, and sculptural space. What remains unpublished is a final as-built area schedule explaining precisely why opening reports round the addition to 6,000 square meters and how the last 2,300-square-meter exhibition figure relates to the earlier 2,200-square-meter gallery-and-terrace program.
