Ancient mossy bridges can perfectly complement rural or river scenes. These mysteriously old bended bridges are human’s ways for traversing through landscapes which are wild otherwise. An interesting fact to be noted here is that archs are only kept in correct position through their own weights i.e.
stones which support an arch cannot stay in position unless the stones which are above them weighs them down. Even though effective as well as sturdy, the process of building them was very complicated as it involved many difficult processes.
