The restoration work on the walls of the Capilla del Sagrario at the Collegiate Church of Briviesca (Burgos) can be visited between May 14 and September 30, in groups of four people, with prior reservation.

In 2025, urgent stabilization work was carried out on the walls, consisting of the consolidation of renderings and plasters, fixing of the polychromy, cleaning of gold leaf, application of renderings in the most weakened areas (pendentives), sealing of cracks and fissures, filling of cavities, and replacement of mortars in joints and volumes. In May 2026, work began on the pictorial restoration of the walls, restoration of doors and wooden elements, as well as the stained glass and windows of the lantern, following the guidelines of the General Directorate of Cultural Heritage of the Junta of Castile and León, and thanks to the collaboration of ACS Foundation.

"Open for Works" allows visitors to tour the installed scaffolding in small groups and observe the progress of the work, accompanied by restoration technicians.

On May 12, the Chapter House Antechamber and its entrance were inaugurated at the Primate Cathedral, following the completion of restoration and conservation work promoted by the Primate Cathedral, in collaboration with ACS Foundation.

After nearly two years of work, a space of great historical and artistic value has been recovered, preserving one of the most significant pictorial ensembles of the early Renaissance in the Cathedral, created between 1508 and 1511 under the direction of Juan de Borgoña, as well as plasterwork and a polychrome coffered ceiling that formed part of this passageway leading to the Chapter House. Much of the recovered paintings had remained hidden for over 250 years behind cabinets from the 16th and 18th centuries, which have been carefully relocated to the Cathedral’s Museum of Tapestries and Textiles.

Access to the Antechamber and the Chapter House, promoted by Cardinal Cisneros, is through the late Gothic portal, also restored as part of this project, in what was once the former chapel of Saint Elizabeth of Hungary.

The ceremony, held in the Cathedral’s ambulatory, was attended by the Dean of the Cathedral of Toledo, Don Juan Pedro Sánchez Gamero; Don Antonio Sánchez-Barriga Fernández, conservation restorer of the Cathedral; Monsignor Francisco Cerro Chaves, Archbishop of Toledo; and Don Antonio García Ferrer, president of ACS Foundation, in the presence of numerous authorities.

The restoration of the Chapter House was inaugurated in 2019, also with the collaboration of ACS Foundation, and with this intervention, the work to restore the full integrity, color, and unity of the Cisneros ensemble is completed, coinciding with the celebration of the 800th anniversary of the Primate Cathedral.

On May 6, the publication Hispania Nostra 50 Years: A Journey Toward the Future was presented in the Clara Campoamor room of the Congress of Deputies, on the occasion of the institution’s anniversary commemoration, with the collaboration of ACS Foundation. The event was attended by the president of Hispania Nostra, Araceli Pereda; the president of ACS Foundation, Antonio García Ferrer; the deputy for Palencia in Congress, Mª Luz Martínez Seijo; and Alfonso Muñoz Cosme, a member of the scientific committee of the Red List.

During the event, the approval on November 11, 2025, of a non-legislative proposal in the Congress of Deputies was highlighted. This proposal recognizes Hispania Nostra’s trajectory in the defense of heritage, as well as the importance of the various channels that Hispania Nostra offers to society to participate in heritage conservation, such as the Red List or the crowdfunding program.

On April 28, the exhibition "Hispania Nostra – 50 Years Committed to Heritage"; was inaugurated at the headquarters of the Official College of Architects of Madrid (COAM) to mark five decades of continuous work (1976–2026) in favor of the protection and defense of cultural and natural heritage.

The exhibition offers a journey through the institution's origins and its territorial structure, as well as its areas of work, including best practices, recognitions, the Red List and the Green List, the heritage education program, the crowdfunding program, and its volunteers and collaborators.

The opening ceremony was attended by Araceli Pereda, President of Hispania Nostra; Ernest Urtasun, Minister of Culture and Sports; Sigfrido Herráez, Dean of COAM; Inmaculada Ballesteros, Director of ACE; Antonio García Ferrer, President of the ACS Foundation; and José Mayor Oreja, Director of the ACS Foundation.

With the support of ACS Foundation and Acción Cultural Española, the exhibition will remain open throughout the month of May at COAM (C/Hortaleza 63, Madrid) and will later travel to other Spanish cities.

Within the framework of the collaboration agreement between the Fundación Santa María la Real del Patrimonio Histórico and ACS Foundation, the volumes dedicated to the province of Lérida, which are part of the Encyclopedia of Romanesque Art in the Iberian Peninsula, have been published.

The work, structured in four volumes, presents the results of an exhaustive cataloguing and analysis of the Romanesque heritage preserved in the province. More than sixty specialists—including historians, architects, photographers, and graphic designers— have participated in its production, studying nearly 1,000 Romanesque testimonies. Each of these is accompanied by its corresponding historical-artistic study and documented with over 40,000 photographs and approximately 1,000 floor plans.

The contents are organised by county (Volume I: introductory articles and the counties of Alt Urgell, Cerdanya, and Vall d'Aran; Volume II: Alta Ribagorça, Pallars Sobirà, and Pallars Jussà; Volume III: Solsonès, Noguera, Pla d'Urgell, and Garrigues; Volume IV: Segrià, Segarra, Urgell, general bibliography, and onomastic and toponymic indices) and aim to serve as a reference for preserving the historical and artistic richness of the province of Lérida.
