Some houses have beautiful Art Nouveau balconies, like the one you see in this picture. Have a look at the second photo to see a detail.
Art Nouveau was a style that developed between the end of the 19th and the beginning of the 20th century.
Fondest memory: In the basilica of Notre-Dame you can read this panel that commemorates people who were killed in the 20th century because they were Christians, such as Maximilian Kolbe or Edith Stein.
If you are driving to Boulogne you will be pleased to know that there is parking everywhere!!
There are several parking stations, various outdoor parking areas and parking on most streets as well.
Fondest memory: At certain times of the week you will have to pay for parking, but for example the street parking near our hotel was free after 7pm on a Saturday and all day Sunday.
We parked in a parking station near our hotel when we arrived on the Saturday morning, and for almost 10 hours parking it only cost 5 euros. (This parking station was closed on a Sunday, but others are open.)
Favorite thing: The top of the town walls has been arranged as an area for walking and having rest. There is a path surrounded by grass and trees, with benches here and there.
