This is, allegedly, the only place in the world where you can visit a colony of nesting Mute Swans. (Trust me, they are not mute). A Benedictine monastery was established at Abbotsbury in the 11th century and the monks began farming swans - which often featured at medieval banquets. The monks have long gone, but the swans are still there (different ones, obviously). If you visit Abbotsbury Swannery these days, you'll find about 600 swans, all free to roam. The colony is established adjacent to a shallow lagoon, the Fleet, which lies behind Chesil Beach. It's a unique location.
