Things to Do in Cergy

Modern cathedral built in the 1960s, known for its striking concrete architecture and stained-glass windows by artists including Alfred Manessier.

🕐 Monday-Saturday 9am-6pm, Sunday 10am-7pm

💡 Visit during late afternoon for the best light through the stained glass; the crypt's small exhibition on local history is free too.

A large, formal French garden with lawns, flowerbeds, a pond and walking paths, originally part of the prefecture building grounds.

🕐 Daily, 8am to sunset

💡 Go early on weekend mornings when it's quiet and you might spot herons by the pond.

A large leisure park with a lake, walking and cycling trails, and free public spaces for picnics and sports. Swimming and water sports are paid, but the park itself costs nothing.

💡 Bring a picnic and head to the small beach area on the north shore – it's free and rarely crowded on weekdays.

💡 Start at the southern end near the Préfecture and walk north – the view from the tower is worth the climb, and it's free on the first Sunday of each month.
