Laon is a charming French town in Picardy. Built on atop a hill, Laon has been endowed with countless medieval monuments, as well as lovely hotels and mansions dating back to previous centuries. The city is divided into two distinct parts: the upper town and lower town. Laon is very famous for its cathedral towering above the city. The River Ardon runs criss-crosses through the south of Laon. Finally, walls have been surrounding the entire city since the eleventh century.
