Destroyed 17 times, the architecture of the abbey of Saint-Riquier is heterogeneous. Go in search of traces of this rich and tumultuous past with us! We will dive into the Carolingian era with the foundations of the site then we will take height with the flamboyant Gothic of the abbey to finally discover an unknown aspect, the small seminary of neoclassical style. Our stroll will also lead us to meet 16th century murals, classified as Historical Monuments and preserved in a private chapel, which will reveal secrets dating back 1400 years.
