The SS Ayrfield, a 102-year-old transport ship sank off the coast of Australia. A forest (or thicket, as the Australians would say) has grown within its hull.
According to Wikimedia Commons, the SS Ayrfield, originally the SS Corrimal, was a steel-hulled steamship, built in the United Kingdom in 1911 and registered at Sydney in 1912. Purchased by the Commonwealth Government, it was used to transport supplies to American troops stationed in the Pacific during the second world war.
