Nice observation tower but not very suitable for telescopes. Binoculars are preferable. The windows are in the way but avoid disturbing the wildlife and protect from the rain. The Duer is also a walk along the gulf on the waters of which many migratory birds, among others, meet. Too bad we can't put some very recent photos here.

The Duer ornithological reserve is an old salt pan now inhabited by tens of thousands of birds. From the two hides installed occasionally, it is possible to observe specimens throughout the year. In winter, geese and teal replace the stilts and terns that camp there in the summer. Observatory number 1 is located a little further east of the salt pan.

Pointe de Brouel is the westernmost part of the Island of Arz (Morbihan). This similarity in name with the nearby Pointe de Brouel on Île aux Moines originated four thousand years before our era, when the two islands were still connected by an isthmus. According to a legend, a young man from the Île d'Arz was madly in love with a young girl from the Île aux Moines, but her parents were opposed to his marriage and decided to entrust him to the monks. His beauty, however, joined him every day. The parents asked the superior of the monastery to chastise the couple. One evening, while Beauty was joining her lover on the isthmus, the sea separated the two islands and drowned the young girl.
