Lighthouses are a vital link between the land and the sea. Apart from being photographically attractive and often historically rich, they are usually located at spectacular points or clifftops on exposed coastlines. These photos of mine have been taken in Australia and in the US (Hawaii).
A very nice gallery. I started collecting light houses (or light towers, actually) once, but I soon realized that it'd be kind of difficult to get to see a lot of them without having a car. So I modified the project, and started collecting tall buildings instead:http://www.pbase.com/mistermattias/phallus. I envy you for getting to see all these cool light houses. Keep up the good work!
