For a small limestone island (approximately 620 metres in diameter, covering 86 acres) it does have a lot of interesting features and areas. As you will see from the map below, we have several nature reserves as well as a gull colony. There is a water tank to provide running water to the buildings and solar panels to provide electricity (the island has its own mini grid). There is a solar panel powered lighthouse, a barracks, a foghorn station, keepers house and farmhouse. The blue lines map out a defined track around the island. There are two jetty and north facing beach. It is a real gem in the Bristol channel.
Thank you to everyone that worked on the DAPTEC Flat Holm project and to all the kids from Mount Stuart primary school, Cardiff that helped us test the exhibit.
