The De Bosset Bridge is one of the most important attractions according to this website – Kefalonia, Grecia. It represents one of the largest stone bridges in the world. It goes out in the sea and gathers together tourists from all over the world since the nineteenth century. The bridge is not natural though. In fact, it was built by a Swiss engineer. Due to his contribution, the engineer became a local governor. As you get on the bridge, you will also be surprised by the symmetrical obelisk rising from the waters. It is entirely made of carved rocks as well.
