La Sienne overlook

Highlight • Viewpoint

The tidal estuary of the Sienne river runs parallel to the road and offers several scenic overlooks.

Tip by

7.33 km

From this overlook that shows the majestic remaining arches of the La Roque bridge, there are three parallel options heading north-west: the road to the old La Roque bridge that turns into Rue de la Sienne, the main Departmental Road 650, and a narrow unpaved path that runs closer to the river and can be marshy and overgrown.

Roque Bridge

Highlight • Historical Site

The beautiful bridge is located at the confluence of the Siena and Soulles rivers. During the Second World War there were several attempts to destroy it. They wanted to prevent the Germans from retreating.
It was bombed unsuccessfully for the first time on April 23, 1944, then regularly by four Royal Air Force bombers until 14/15. June, when three of the eleven arches collapsed.

Regnéville-sur-Mer

Highlight • Settlement

This little beach harbor at the mouth of the Sienne, which used to be one of the most prosperous on the entire coast, fell into disrepair when the harbor silted up. Now the 12th-century castle ruins are the setting for exhibitions in summer.

The church with its simple rectangular plan dates from the middle of the 13th century. The choir was vaulted in the 19th century.
The tower, from the second half of the 13th century, has a single ogival window on each side2. It is surmounted by an octagonal spire in truncated stone, with four corner pinnacles inspired by those of Coutances.
The bell tower is classified as a Historic Monument by order of May 14, 1937.
