Capelinhos Volcano Interpretation Centre

A museum buried in the ash of the volcano it explains, built beside the half-buried Capelinhos lighthouse on the western tip of Faial in the Azores.

The eruption that made this place

On 27 September 1957 the sea off the western tip of Faial began to boil. The eruption of the Capelinhos volcano lasted thirteen months, until October 1958. It built a new islet — briefly a separate island — that fused with Faial and added about 2.4 square kilometres of new land to the island. Ash destroyed some 300 houses in the parishes of Capelo and Praia do Norte, and around 2,000 people were evacuated. Remarkably, nobody was killed.

The human aftershock lasted longer than the geological one. With farms buried, emigration became the way out: the United States passed the Azorean Refugee Act in September 1958, co-sponsored in the Senate by John F. Kennedy, authorising 1,500 of the displaced to emigrate. The parishes around the volcano lost about half their people.

The lighthouse

The Capelinhos lighthouse had watched this coast since 1903 — work on it began in 1894, and it was inaugurated on 1 August 1903. It was the only substantial building standing at the point when the eruption came. The light was extinguished on 29 November 1957 as ash piled against the walls; by the end, the keeper’s house and tower were buried up to the second floor. The tower still stands in that state today, its base below the ash line, and it has become the symbol of the island.

A building that refuses to be seen

Fifty years after the eruption, the Azores regional government built an interpretation centre on the site, designed by architect Nuno Ribeiro Lopes (project 2003–2005, built 2006–2008). The design decision was radical restraint: the building sits in front of the lighthouse at the level of the ground before the eruption, so it lies entirely buried in the volcanic sands, founded on the original terrain. A group of connected volumes runs underground and links through to the lighthouse itself, so the visit ends inside the older building. Above ground, almost nothing interrupts the ash landscape the eruption left behind.

Inside, and visiting

The exhibitions work through the eruption itself — including film of the event and a holographic projection — the formation of the Azores, volcanism around the world, and the history of Azorean lighthouses, drawing on a collection of geological samples. The visit finishes with a climb up the lighthouse tower. The centre was nominated for the European Museum of the Year Award in 2012, and it now belongs to Portugal’s Ciência Viva network of science centres, within the Faial Natural Park.
