The castle is nicknamed 'The Fish Castle' because of its proximity to the sea and the fishing grounds of Portland Harbour.
Construction materials included stones salvaged from the dissolution of the nearby Bindon Abbey.
The fort was abandoned by the military in 1665 due to mounting repair costs and structural instability.
A dedicated conservation project in 2012 reinforced the ruins to prevent further structural failure and allow public access.
The castle grounds contain a community garden specifically planted with species that thrive in the coastal microclimate.
Archaeological surveys have identified extensive underground fortifications that were largely lost to erosion in the 19th and 20th centuries.
Sandsfoot Castle is an artillery fort constructed in 1539 by order of King Henry VIII to protect the Dorset coastline from potential French or Spanish invasion. Situated on the cliffs overlooking Portland Harbour, the structure is currently maintained as a stabilized ruin within a public garden. It formed part of a pair with Portland Castle, designed to defend the anchorage of Portland Roads. The site historically suffered from severe coastal erosion, leading to the collapse of significant portions of the masonry into the sea. Today, visitors can access the grounds and the adjacent Sandsfoot Gardens, which feature a café and coastal views. The masonry features distinct Tudor architectural elements despite its dilapidated state. The site is situated along the Rodwell Trail, a former railway line converted into a path.

Walk the connecting Rodwell Trail for elevated views of the castle from different angles.
Check the local coastal weather forecast before visiting, as the site is fully exposed to high winds from the English Channel.
Visit the adjacent cafe for local information on walking paths extending toward the ferry terminal.
Do not attempt to climb or touch the unstable historical masonry, as the structures are monitored for safety and conservation.
The internal ruin area may be restricted during periods of severe weather or essential masonry maintenance.
