The maps present the plan of Porth Harbour in 2000 and the current one. Overall, the changes were made to convert a harbour into a residential-friendly area, adding some extra amenities. A new hotel is present today in the place of former disused castle, along with new restrooms and showers area. Of particular note is that a river covered the vast majority of available space.
In 2000, there was a castle located in the southeastern corner of the harbour, with public beach situated nearby. The space for Marina and fishing boats was interlinked with river, which located opposite to each other. Additionally, there were restrooms and car park beside the former, whereas the latter sits with another bigger car park. Interestingly, both spaces for parking were joined with main road. In the northern side, there is a dock with passenger ferries, which are located next to another public beach.
Today, some changes were made to create cozy atmosphere for users. The castle, which was out of use, has given its space for a new hotel, with its public beach to private that owned by hotel itself. There is a new area for cafes and shops, which is located near to lifeboat. Another restroom area is added just beside the bigger car park in the southwestern side. It is also worth noting that fishing boats and Marina are exchanged their places with each other. Ultimately, the dock for passenger ferries has been expanded.
