The city of Cambrai is the central square of the town and is a beautiful historical monument opened in 1932. During the Great War, the old town hall, or "hotel de ville" in French was destroyed but was rebuilt in neoclassical style. The Greek facade has a belfry with two giant Moors who ring the bell every hour. Named Martin and Martine, they are the protectors of the city. The living room is beautiful and if you want you can go and visit it but you have to make an appointment. I found it very large considering the small size of the city, but in the past, Cambrai was a very important industrial area of northern France.
Cambrai station is very close to the city center and is quite small but it is well connected to the rest of the region. There are only two ticket booths and when I arrived train had been canceled and it took time to get a new route but in the end the staff was helpful and let me get on the next train first. At regional level the station is linked with Lille and from there you can catch the Eurostar to Brussels, London and TGV to Paris, Douai, Valenciennes and Reims. To go to Paris, the quickest way is to go through Douai which takes a bit more than an hour and a half. The prices online are lower if you buy at least two weeks before. It takes less than an hour to get to Lille. Built in the 19th century, the station is beautiful and is still in the old building and on the service level you will find a restaurant and a newsagent.
A belfry is a bell tower that does not belong to a church. It symbolizes the freedoms acquired by the independent cities of a feudal lord and the church. The belfry bell served not only for its bell, but also for the city archive, and a safe for the treasure. The belfry of Cambrai is located next to the Town Hall Square. It was built in the mid-fifteenth century, and has a height of 62 meters. There was another from the eleventh century, but the Emperor Henri ordered it to be destroyed. The bells were used to call people to the the courts to reach their judgments, to call to public assemblie. The belfry is classed with 23 other towns of Belgium and northern France as part of the UNESCO World Heritage. During the First World War it was burned, and the great bell fell to the ground. But now it has once more been restored.
