A lively street festival organised by the local Scout Group, Ataque ao Pâmpano takes place along the main avenue of Boidobra, featuring regional entertainment groups – from drumming ensembles to university musical groups (tunas) – as well as food stalls offering local specialities and traditional crafts.
The event also aims to highlight the legend behind the origin of the Chapel of Nossa Senhora da Estrela (Our Lady of the Star).
According to local tradition, the chapel was built by Egas Moniz, inspired by a legendary encounter. The story goes that during the reconquest of lands from the Moors, the wild and uncultivated banks of the Zêzere River were dense with undergrowth and rich in game. While hunting in this area, Egas Moniz was attacked by a fearsome beast known as a pâmpano. Facing certain death, he called upon Our Lady, to whom he was deeply devoted, promising to build her a chapel if she saved him. Escaping unharmed, he fulfilled his vow by founding the chapel, naming it after the morning star (estrela de alva) that shone brightly in the sky at the moment of his deliverance.
In 2025, the festival took place on 2, 3 and 4 May in Boidobra.
