Just outside the town centre stretches the Audomarois marsh, a UNESCO-recognised wetland shaped by centuries of market gardening. Exploring it by boat, bike or on foot reveals a calm, green world criss-crossed by water.
Notre-Dame Cathedral dominates the town with quiet confidence. Inside, the famous astronomical clock and the play of light give the visit a contemplative feel, perfectly in tune with Saint-Omer’s gentle pace.
Water is everywhere here. Walking along the canals or taking a short boat trip offers a different perspective on the town — one that naturally slows you down and reconnects you with the landscape.
Saint-Omer’s historic centre is compact and easy to explore. Townhouses, small squares and discreet heritage details appear as you wander, without the need for a fixed itinerary.
Markets, small restaurants and everyday encounters give Saint-Omer its charm. This is a place to enjoy regional flavours, talk to locals and feel part of the town, even for a short stay.
