In 1928, the architect and historian Josep Puig i Cadafalch (1867-1956) restored the Romanesque Church of Santa Cecilia de Montserrat. The architect reconstructed the interior of the church and found inspiration in the Carolingian liturgy from the time of the foundation of the monastery. He added three wooden beams and hung Romanesque-style curtains to cover altars and apses when no ceremonies were taking place. The central altar was adorned by a metallic front relief, inspired by the Romanesque lintel in the Church of Sant Genís de Fontanes (Roussillon). On this relief, Josep Pich i Pon, the politician who paid for the restoration work, had a votive inscription made.

Opening ceremony for the restoration of Santa Cecilia de Montserrat, August 30th 1931, presided over by Abbot Antoni M. Marcet and the architect Josep Puig i Cadafalch.

1940. After the end of the Spanish Civil War, two communities of Benedictine nuns from Mataró and Santa Clara de Barcelona settled in Santa Cecilia de Montserrat. They merged into one community, called Sant Benet de Montserrat, and resided in Santa Cecilia until 1954.

1954-2000. Over this fifty-year period, the community of Montserrat used Santa Cecília as a place to host group meetings, especially retreats for young people.
