In the Marais, more specifically in what is known as the Saint Paul quartier, you can still find some of the old medieval half-timbered houses that were not flattened by Baron Haussmann's "new" city plans in the 19th century. This one is at the corner of Rue des Barres and Rue du Grenier sur l'Eau, if you're passing by that way and would like to see for yourself. Then, treat yourself to a leisurely stroll around that whole area... the architecture is really wonderful, with a few more of these buildings and some of the ancient carved stone ones, like this one.
