This pre-Romanesque building houses a rectangular nave with a wooden framed ceiling and a quadrangular apse. The circular Lombard belfry was added in the 12th century and is one of the few examples of its kind in the Pyrenees.

The building was decorated with 12th-century Romanesque mural paintings by the master painter of Santa Coloma. These paintings left the country in 1930 and were recovered by the Andorran Government in 2007. At present, only the Agnus Dei flanked by two angels and the geometric decoration framing the overhanging arch remain in the church.

The church preserves a polychrome wood statue of Our Lady of the Remedies ( 12th to 13th centuries) and a Baroque altarpiece ( 18th century) dedicated to Saint Coloma, the church’s patron saint.

The church’s location means visitors can enjoy Santa Coloma old town with its traditional buildings, as well as Els Russos tower, designed by César Martinell, one of Andorra’s granite architecture examples.
