Traces of the first Saint-Martin chapel in Colmar date back to around the year 1000. Excavations carried out in 1972 revealed the presence of an 11th-century sanctuary that was destroyed by fire in 1106 and replaced by a Romanesque church.
The current Gothic collegiate church was rebuilt between 1235 and 1365. The use of Vosges sandstone in warm tones ranging from light yellow to violet gives the church all its beauty. The building was never fully completed, as the originally planned north tower is still missing.
