The nave of the little church of San Romerio ("San Rumeri" in the dialect of the Puschlav) was built in the 11th century. Choir and tower were added in the 15th to 16th century.

The simple church was first mentioned in 1055, located on an important hem road in a scenic magnificent location, 800m above Lake Poschiavo in an altitude of 1.800 meters. In time, a monastery and a hospice were created, inhabited by monks and nuns. The alp became an important and popular place for centuries which was frequented by a vast variety of people.

The small romanesque church stands on the precipice of a hard rock slide. It is under the protection of the monuments of the canton of Grisons and taken care of by the monument conservation department of the community of Brusio. It belongs to the diocese of the catholic church of Milan Madonna di Tirano.

Through a small window, a ray of sunlight shines into the church exactly on the 1st of October, the day of St. Remigius. Only in 1998 and by chance frescoes from the 11th century were discovered on the opposite wall of the window, which are illuminated by the sunlight.

The key to the small church is kept in the San Romerio hostel, where you are welcome to ask for it when interested in visiting the church.
