The Diocese of Jaca will celebrate its 950th anniversary in 2027

The Diocese of Jaca has formed a three-person commission to organize celebrations for the 950th anniversary of its establishment as a stable episcopal see. The diocese identifies the year 1077 as the moment Jaca consolidated its role as a permanent seat, following the earlier existence of the Bishopric of Aragon, which was located in various places including Sasabe, Siresa, and San Juan de la Peña.

The commission members include Belén Luque Herrán, director of the Diocesan Museum, who will manage exhibitions; Ricardo Mur Saura, a professor and historian, who will oversee lectures and publications; and Jesús Lizalde Giménez, dean of the cathedral, who will manage institutional matters and music.

The planned program includes an opening Mass in early March, various lectures throughout the diocese, organ and vocal concerts, and several exhibitions, some of which will travel. The anniversary celebrations will conclude with a closing ceremony.
