The Haut-Marais bower

The Charmille is a plantation of trees called hornbeams, planted in double rows so that as the trees grow they form a canopy supported on a metal structure.The Charmille du Haut-Marêt (or Haut-Marais) at La Reid is known as the longest in Europe, at 573 metres (and even then it was twice as long when it was planted!); it has about 4,700 hornbeam plants, which are maintained by the nearby School of Agronomy (one month's work per year by a team of young students supervised by teachers).The Charmille is accessible free of charge all year round. It is a pleasant walk in all seasons, as the colours vary from white to different greens and all shades of gold!
