Near the Church of St. Ouen, a replica of a runestone commemorates Rouen’s Viking history. Vikings (some of my ancestors maybe?) took over the city of Rouen many times and went home in the winter. Then they got smart and appreciated the soil and easier climate, and settled here.
The Church of St. Ouen, a Gothic building started in the 14th century, is well-supplied with gargoyles to watch over things. Gargoyles seem to be everywhere around Rouen — on St. Ouen’s, Rouen Cathedral, the hall of justice — pretty scary at night!
