This street, with its series of narrow alleys, dates back to the 11C. It was then situated outside the fortified city walls, hence its name ("Outside the Castle").At 114-116, note the little porch flanked by two modern Corinthian columns leading to Cour St-Antoine, prettily restored by Charles Vandenhove at the end of the 1970s. the monument in blue stone is by Anne and Patrick Poirier.
