The Church of San Marcellino, located in the hamlet of Rigomagno di Sinalunga, is a fine example of religious architecture dating back to the 11th century. Characterized by a Romanesque-style façade, it is built with square stone drafts that give it a solid and imposing appearance.
The central portal is architraved, that is, surmounted by a rectilinear lintel, and is embellished by a round arch above it, typical of the Romanesque style that focuses on the curved and perfect line of the semi-circle. The verticality of the structure is further accentuated by the presence of a terminal mullioned window, an architectural element consisting of two side-by-side openings separated by a column or other support, which is one of the distinctive elements of Romanesque churches.
Inside, the church features a single nave, a space that leads worshippers and visitors alike into an intimate and cozy environment where the gaze can easily rise upward in contemplation. An integral part of the artistic heritage of the Church of San Marcellino are the two wall paintings created by anonymous artists working in the 17th century.
These artists are situated within the figurative culture of the time, influenced by the Nasini workshop, a family of painters who gave shape and color to local artistic expressions during the 17th century. The paintings depict the Madonna and Child and Saints, markedly devotional subjects that reflect the faith and spirituality of the Rigomagno community and still retain their charm and sacred significance for the viewer.
