Welcome to Portland Museum

“The treasure on the Island”

Portland Museum is delighted to announce that we will be open during October 2021 from Tuesday to Saturday 10:30 – 16:00 (last entry 15:30).

Dinosaurs, shipwrecks and smugglers, Roman and Viking invasions, stone carving, seafaring, ground breaking scientists and world-famous authors: Portland Museum packs in an astonishing collection that reflects the history and people of this exceptional island community!

Portland Museum is a gem – tucked away in a beautiful corner of the island in two cottages dating to the seventeenth century, a stone’s throw from Rufus Castle and the stunning Church Ope Cove, on the South West Coast Path.

Although joined to the mainland by a tombolo, (a wave formed beach) the island has always been regarded, and self-identified, as somewhere different and the museum’s collection reflects this.

Staffed by volunteers from the local community, Portland Museum looks forward to welcoming visitors eager to find out about author Thomas Hardy and museum founder Dr Marie Stopes’ connections to the island. Ancient superstitions in witchcraft, getting up close and personal with a Jurassic sea monster or finding out about the Nanny Diamonds, Portland Museum has something to interest everyone! 


If you would like to join our friendly team of volunteers, please contact our museum manager, Lucy, by phone or email.
