Chiswell Earthworks, Land sculpture in Portland, England
Chiswell Earthworks is a sculpture made of five stepped terraces built from different stones found in Portland, positioned above Chesil Cove at the southern end of the beach. The terraces use local geological materials to create a layered form that sits at the water's edge.
This sculpture was created between 1986 and 1993 by artist John Maine, following a proposal from Margaret Somerville who owned the Chesil Gallery. The work represents an important artistic intervention along Portland's shoreline.
The work came to life through collaboration with local people who helped shape its form and placement. Today visitors experience how it connects the community to the stone and geology that define Portland.
This sculpture sits at the southern tip of Chesil Beach and is accessible by walking along the shoreline to its endpoint. The best time to visit is at low tide when you can see more of both the structure and the surrounding beach.
Each terrace displays different stone types that occur naturally beneath Portland's surface, turning the installation into a kind of geological textbook carved into the landscape. This layered arrangement reveals what lies underneath the ground you walk on.
