This is one of the Structures which are part of the Structures on the Edge Project - look it up on the Internet, it's worth it.

You find the Sound Tower in the sandhills from the Chapel Six Marshes Car Park. It's a stark structure but with a secret. It amplifies the sound around for you but can you also see out to the seashore. As well as a car park and picnic site there is a wetland area with open water, sand dunes, shrubs and trees which all provide homes for a variety of wildlife. The site lies within the Lincolnshire Coastal Country Park.
