- Lime Kilns of Rey - Maritime Museum:
- Lime Kilns: Benefiting from the presence of a carboniferous limestone deposits, the country has Montmartin from the 16th century in many lime kilns. Built between 1852 and 1854 on plans by engineer Pierre Simoneau, the four large lime kilns were built to support the old face of the limestone quarry of Rey. The dry harbor Regnéville then saw its traffic grow: schooners unload coal from Wales, other ships leave the local limestone to the Channel Islands and Brittany coast. This is to provide lime amendment of these countries to lands west Armorican acids. Lime kilns shall remain in business only about thirty years: the liming is practiced less and lime production will be abandoned in the late 1880s.
- Maritime Museum: Maritime Museum traces the history of maritime and industrial Regnéville-sur-Mer. Through models and reconstructions, the museum evokes different production techniques and use of lime since antiquity. The museum also reflects the maritime history of the village. From the Middle Ages, trade is dense with the Medieval Fair, founded by John Lackland. Objects, marine works, tools and works of art evoke navigation and life onboard. The daily lives of seafarers, it is also that of those who carry the "coastal trade": rigger, boatswain, sailing or tailpiece. The last rope Regnéville, closed in 1925, was reconstituted on site and open to visitors. The museum gives obviously an important place in the coasting trade, since this form of navigation was particularly here in use. It presents the types of ships that frequented the port Regnéville in the late 19th century, the boundaries of the demarcation and cabotage, the rules for this type of navigation. Paintings, models, wreck, sails old can evoke this activity. A film about the history of the medieval castle of Regnéville, erected there to protect a busy trading port, allows to link the two themes.
- Medieval Castle:
- A castle built "feet in water" whose story began in the 14th century.
- Castle Regnéville or a tumultuous history: First residence of Charles the second the Bad, king of Navarre, the fortress helped protect merchant before becoming a major place of the Hundred Years War in Normandy. These are the wars of religion which, by destroying virtually the entire site, will give the tower its characteristic shape.
