The Church of San Martín, located in the small town of San Martín de Unx, Navarre, is a remarkable example of Romanesque architecture from the 12th century. Perched on a hillside, the church offers not only an impressive architectural experience but also panoramic views of the surrounding countryside. Its historical and artistic value makes it a key attraction for those interested in medieval heritage.

The church was built during a period when Romanesque art flourished in Navarre, heavily influenced by the region’s connection to the Camino de Santiago. Dedicated to Saint Martin of Tours, a patron saint widely venerated in medieval Europe, the church served as a center for religious worship and community gatherings.

Architecturally, the Church of San Martín showcases the typical features of the Romanesque style. The exterior is marked by simplicity and solidity, with a robust stone construction and a modest yet elegant façade. The semi-circular arches and the finely sculpted capitals of the doorway are noteworthy for their intricate decorative details, which include floral motifs and biblical scenes.

The interior consists of a single nave covered with a barrel vault, supported by thick walls and buttresses. The apse, with its semi-circular shape, is adorned with small, intricately carved windows that allow light to filter in, creating an atmosphere of serenity and reverence. Some Gothic elements were later incorporated into the church during subsequent renovations, reflecting the evolving architectural trends of the time.

One of the most interesting aspects of the church is its crypt, a rare feature in Romanesque buildings in the region. The crypt, located beneath the main altar, is accessible to visitors and showcases remarkable stonework and a unique layout.
