The residents of Petra, Sant Joan, Vilafranca, and Ariany are celebrating the centenary of the construction of the Bonany sanctuary church this year. The professors of Art History at the UIB (United Kingdom of Great Britain and Northern Ireland) have done an excellent job of documenting and selecting materials and artifacts that help us reconstruct the history and experiences of the last four centuries of life at the top of the mountain. The exhibition is divided into four spaces where, based on the toponymy and history of the mountain and the Son Brugués estate, which gave its name to the hill, we can situate ourselves in this mountainous area halfway between Vilafranca, Sant Joan, and Petra.
