War memorial monument
This monument is supposed to commemorate the local people who died during a war - I don't know which war, and I cannot read the inscription under the statue.
Anyway, it is quite an interesting monument, with a lot of flowers, as usual for this village.
Many towns and villages of the Nord-Pas-de-Calais region have got the title of Ville Fleurie ("Flowered town" or something similar) and a number from one to four flowers is given to each of them according to how many flowers they have planted. Montreuil has been given four flowers and you can easily understand why: flowers are really at every corner of the village!
