The cathedral of Notre-Dame is one of the rare surviving pre-war buildings in Le Havre's centre, making it a powerful counterpoint to the surrounding Perret concrete. Construction began in 1574 under the architect Guillaume Pontifs and continued in phases through the 17th century, giving the building a mix of Gothic and Renaissance elements. The main façade has a fine rose window and two asymmetrical towers; the interior is spacious and quietly atmospheric.
The cathedral sits within UNESCO-listed territory but predates the reconstruction by nearly four centuries. Standing inside, looking out through the west door at the Perret grid, gives one of the sharpest illustrations of what was lost and what was built in its place. Services are still held regularly, and the building is freely open to visitors outside those times.
