The story

Semana Grande San Sebastian in San Sebastian

San Sebastian's Semana Grande (Aste Nagusia) centers on a nightly international fireworks competition over the Bay of La Concha, judged across successive evenings, alongside txosnas, temporary festival stalls run by neighborhood and cultural associations, and Basque-specific giant-figure processions and traditional rural sports demonstrations throughout the week.

San Sebastian's Semana Grande, known in Basque as Aste Nagusia, centers on an international fireworks competition held over the Bay of La Concha, in which teams from different countries compete on successive nights to stage the most impressive display, launched from barges just offshore and watched by crowds packed along the bay's promenades and beaches.

What is special

The part that makes it specific.

01

The place changes

The nightly international fireworks competition over the Bay of La Concha is Semana Grande's signature event, giving the week a structured, judged spine that most summer civic festivals lack, with teams from different countries competing across successive evenings rather than a single closing display

02

The mystery stays covered

The txosna system, temporary stalls run independently by neighborhood, cultural, and political associations rather than the municipality, gives the week a grassroots organizational character distinct from centrally run festivals elsewhere in Spain, alongside Basque-specific Kiliki and Zimuges giant-figure processions
