Brest – a rather gray city, with green oases interspersed throughout. This garden is no exception; I celebrate it and look forward to more of these flourishing examples!

The old church of Saint-Marc still stands and bears witness to a long history. It is indeed attested that religious occupation of the site dates back to the 15th century and that the building was constructed in the 17th century. Small, narrow, and dilapidated, it was supplanted by the new church built higher up, but was still frequented, particularly by fishermen who plied their trade in the cove which, before land reclamation, was right next door. A vestige that almost disappeared: The building took the name Notre-Dame du Bon-Port chapel in the 1870s. Restored several times, it also almost disappeared many times, notably due to the explosion of the Ocean Liberty ship in 1947. Saint-Marc suffered greatly from the bombings, to the point that the chapel is today one of the few visible remains of the village of yesteryear. Despite this, it is not listed, and its future remains uncertain: its roof needs to be redone, and it is only open for two masses per year, on Ascension Thursday and August 15th, plus a few special concerts. Having been built before the separation of Church and State, it is owned by the City of Brest. Finally, it should be noted that its stained-glass windows were created by a woman, Adeline Bony, wife of Jacques Bony, who created the stained-glass windows of the Saint-Louis church.
