Plouha has many notable medieval sites ranging from chapels and churches to manoires and kers, including The Chapel of Kermaria (Kermaria an Iskuit).
World War II
Plouha's beaches were the sight of several resistance efforts, notably as part of the Comet line, a resistance group that sheltered Allied troops and helped them return to Great Britain. The Bonaparte beach near Plouha was the site for the evacuations by sea organized by the Shelburne Escape Line and residents of Plouha. In 1944, more than 100 downed allied airmen were evacuated by Royal Navy motor gunboats from Bonaparte Beach to Dartmouth, England.[4]
