Church of Santiago, Luna

The Church of Santiago is a Romanesque building with a rectangular layout, a single nave, and a semicircular apse containing a crypt beneath the floor. The structure was built using carefully cut stone blocks fitted with great precision.

The building was constructed during the 12th century following the architectural principles and building methods used for medieval churches in Aragon. Its design reflects the techniques and approaches common to religious structures of that era and region.

The building displays decorative elements such as checkerboard patterns and sculpted corbels showing musicians and animals. These ornaments reflect the local interpretation of Romanesque style in this region.

Natural light enters through five arrow-slit windows positioned in different parts of the building, including the apse and walls. These narrow openings create a soft filtered lighting inside the structure.

The entrance portal features three splayed archivolts resting on smooth jambs and simple imposts, creating a distinctive entrance. This portal design demonstrates skilled stone carving and a particular approach to Romanesque architectural forms.
