Riddle of Spiky Bridge
It's just a bridge but it's pretty cool. Built by convicts in 1843, this bridge abruptly pops out of the landscape to baffle passers-by with its odd design.
The bridge was constructed from field stones laid without mortar or cement and the parapet features field stones laid vertically, giving the bridge a spiky appearance.
It's claimed that the spikes were designed to prevent cattle falling over the sides of the bridge, though no one really knows if this is true. There are also the remains of the Governor's cottage on the hill overlooking the unusual bridge.
The bridge is 7.5 km south of Swansea on Tasmania's East Coast, on the western side of the highway opposite the beaches of Great Oyster Bay. Across the Bay are stunning views to the mountains of Freycinet National Park.
