The entire town of Airolo and the village of Fontana are listed in the Inventory of Swiss Heritage Sites. Church In 1877 a fire destroyed almost all of the town, including most of the church dedicated to Santi Nazario e Celso, which had been built in the 12th century and is first documented in 1224. The tower, crowned by a double row of twin arches has survived from the Romanesque building. In 1879 the church was rebuilt, under the auspices of an Uri lawyer based in Airolo, Carl Alois (Luigi) Müller, who was married to Genovefa Lombardi, the daughter of Felice Lombardi, Director of the St Gotthard hospice. There is a marble plaque in the church recording his efforts to get the church rebuilt.
