Dolerite and Lattice in the Cataract Gorge Launceston Tasmania Some thoughtful person built a home or maybe just an office next to the entrance of the Cataract gorge. It is constructed in the Edwardian style similar to many buildings in Launceston however the sloping cut dry dolerite stonework bares a slight resemblance to a Japanese castle standing at the start of a path as it does. Having observed many Japanese tourists looking at the gorge from Kings Bridge it seems this resemblance is not lost on them!
