The two granite quays which protect the harbour date back to the 17th century (North Quay) and 19th century (South Quay) whilst parts of the old wharf date back to the 13th century.

The quays are grade II* listed under English Heritage

Visitors should be aware that Mousehole is still a working harbour and, as such, hazards may be encountered on the quays. In addition, by their nature, the quays provide an uneven surface and may present a trip or slip hazard to the unwary.

Under no circumstances should boat moorings be moved or interfered with unless with the express permission of the harbour master.

As the quays are used for landing fish and shellfish, we regret that dogs are not permitted on the quays (or beaches) at any time of the year.
