The map illustrates changes at Porth Harbor from the past to the present day.
It is evident that the harbor has undergone significant developments, shifting from primarily commercial fishing and limited private boating to predominantly recreational use.
Previously, there was a single dock in the northern part of the harbor, situated below a public beach extending further north. Today, while the beach remains unchanged, an additional dock has been constructed to accommodate passenger ferries. Moving south and west from the docks, there used to be a marina for private yachts, along with showers, toilets, and a car park connected to the main north-south road. Currently, the marina has been relocated to the immediate south, but the amenities and car park remain in place.
In the southwest section of the harbor, a new marina has replaced an open area for fishing boats. Adjacent to this marina are new showers and toilets, along with an existing second car park connected to the main road. On the eastern peninsula, where there was previously a lifeboat station and a private beach, there are now cafes, shops, and a smaller road leading to a newly built hotel at the easternmost point.
