The Church of San Martín de Tours in Uncastillo has recently been recognized as a Cultural Asset of Interest (BIC) in the category of Monument by the Government of Aragon, highlighting its historical and architectural value. This recognition adds to its current role as a Center for the Interpretation of Sacred Art of the Pre-Pyrenees.
Recognition as a Cultural Asset of Interest
The declaration of the Church of San Martín de Tours as a Cultural Asset of Interest was formalized by the Government of Aragon, in accordance with Law 3/1999 on Aragonese Cultural Heritage. This process began in July 2025 when the General Directorate of Cultural Heritage initiated the related procedures. The Provincial Commission of Cultural Heritage of Zaragoza approved the declaration in February 2026, and the Government Council ratified the decision at its most recent meeting.
This recognition underscores the historical and cultural importance of the temple, which has witnessed multiple transformations over the centuries. The church, dating back to the Romanesque period, shares chronological similarities with the Cathedral of Jaca, emphasizing its relevance in the context of Aragonese medieval art.
Historical and Architectural Evolution
The earliest documented records of the Church of San Martín de Tours date back to the mid-12th century, although its architecture suggests an earlier construction, possibly from the late 11th century. Elements such as the southern portal and the tympanum of the tower reflect its original Romanesque style. Over time, the temple underwent several construction phases, including a cloister in 1264 and modifications up until the 18th century.
Originally, the church served as a royal chapel until it was transferred to the Bishop of Pamplona by Peter III in 1250. In the 20th century, architect Francisco Pons Sorolla led a significant restoration project that culminated in the removal of the sacristy in 1969.
Current Cultural Function
Currently desacralized, the Church of San Martín de Tours has housed the Center for the Interpretation of Sacred Art of the Pre-Pyrenees since 1999. This cultural space features a permanent exhibition of altarpieces, sculptures, and liturgical objects, not only from Uncastillo but also from other parishes within the Diocese of Jaca, contributing to the preservation and dissemination of the region’s sacred heritage.
