The maps illustrate the transformation of Porth Harbour from 2000 to the present day. Overall, the harbour has seen extensive development, shifting from a primarily functional maritime site to a more tourist-oriented destination with enhanced amenities.
In 2000, the western side of the harbour featured a single car park and a block of showers and toilets, while the central pier housed only a lifeboat station. The eastern peninsula was occupied by a disused castle, and the public beach was accessible to all. The marina for private yachts was located north of the fishing boats, and the dock for passenger ferries remained in the north-east.
Today, the infrastructure has expanded considerably. A second car park and an additional set of showers and toilets have been constructed to the south of the original facilities. The fishing boats and marina have swapped positions, with the marina now located further south. Notably, the central pier now includes a row of cafés and shops alongside the lifeboat station. Furthermore, the disused castle has been converted into a hotel, and the adjacent public beach has been designated as a private beach for hotel guests.
