An impressive stone monument with a large cross, located on the edge of the shipping channel of Grand-Fort-Philippe, near Gravelines. The calvary was built in 1947 to protect the fishermen and in memory of those who were lost at sea. Under the stone arch is a small chapel with a statue of the Virgin Mary and memorial plaques. Every year on August 15th, the place really comes to life: after the procession through the streets, the traditional boat parade stops here for the blessing of the sea. A quiet, atmospheric place to pause and reflect on the difficult fishing history of this coast, with a view of the channel and the sea. Feel free to combine it with a visit to the Musée du Sauvetage in the village.

The Grevelingen Town Hall (Hôtel de ville de Gravelines) is the town hall of the city of Grevelingen in the French Northern Department, located on Place Albert Denvers. There was probably a medieval alderman's house on the same site, which became a town hall in 1789. The building was in poor condition and even threatened to collapse. In 1834, a new town hall was built in Marquise limestone, according to a design by Charles Henry. The building is in neoclassical style. A short staircase leads to the entrance door, behind which are the mayor's room and various offices. There are several rooms on the first floor, such as the banquet hall, the council chamber and a courtroom. The cellars contain a cistern and a storage place for salt, needed for fish preservation. https://en.wikipedia.org/wiki/Gravelines?wprov=sfla1
