The Nyon temple is registered as a Swiss cultural asset of national importance.
The current church was last renovated between 2013-2016. The Romanesque choir dates from the first quarter of the 12th century.
The medieval mural depicting the miracle of Pentecost probably dates from the second half of the 13th century.
The beautiful stained glass windows, apart from the one behind the organ, were created by the artist François de Ribaupierre (1886-1981).
Originally this church was Catholic and was called "Notre-Dame".
