Lonely Planet review
Paris’ oldest standing church, the Romanesque St Germanus of the Fields, was built in the 11th century on the site of a 6th-century abbey and was the dominant place of worship in Paris until the arrival of Notre Dame. It's since been altered many times, but the Chapelle de St-Symphorien (to the right as you enter) was part of the original abbey and is believed to be the resting place of St Germanus (AD 496–576), the first bishop of Paris.
The Merovingian kings were buried here during the 6th and 7th centuries, but their tombs disappeared during the Revolution. Over the western entrance, the bell tower has changed little since 990, although the spire dates only from the 19th century.
