The Crystal Palace Dinosaurs are a unique symbol of the local area. They were built in the 1850s in the grounds of the Crystal Palace and where the first ever life ­sized reconstructions of extinct animals. A bony fish that over thousands of years metamorphoses into a skeletal bridge. Using biomimetic principles in its geometry, the bridge is ultra-lightweight, super-economical, and touches the land lightly. To control access, the bridge has two positions: resting in the middle of the weir and swinging 90 degrees. The bridge enables access to a national heritage of international importance, the Crystal Palace Dinosaur islands.
