“ The central square is decorated by a graceful fountain in the Renaissance style, restored in 1743. Remains of the ramparts and of the château of the dukes of Penthièvre, which belong to the 15th century, still survive. Guingamp is the seat of a sub-prefect and of a tribunal of first instance. It is an important market for dairy-cattle, and its industries include flour-milling, tanning and leather-dressing. Guingamp was the chief town of the countship (subsequently the duchy) of Penthièvre. The Gothic chapel of Grâces, near Guingamp, contains fine sculptures. ”
