A date fixed by the calendar, a programme published in June
The climax of Porto's festivities is the night of 23 to 24 June every year, with 24 June the municipal holiday. Ágora – Cultura e Desporto do Porto runs the official programme: free stages in the centre, parish stages from the evening and a midnight pyromusical display over the Douro. In 2026 the stages stood on Avenida dos Aliados, Largo do Amor de Perdição and Casa da Música. The 2027 line-up, exact stage locations and road closures are published in June; do not treat previous years as a promise.
