Eagle On The Hill is an unbounded locality of Adelaide in the Adelaide Foothills. It borders Mount Osmond and Waterfall Gully.
The village is located on Mount Barker Road, which was formerly the connection from Adelaide to the South Eastern Freeway. Once the freeway was extended through the Heysen Tunnels in 2000, through the ridge underneath Eagle On The Hill, the locality went into a precipitous decline. It is now a relic of its former self; its restaurant, hotel, bottle shop and service stations have all closed, leaving behind a quiet suburb with a small resident population. Eagle On The Hill is now a very popular spot for downhill speedboarders who travel down the road at speeds close to 65 kilometres per hour.
Hotel
The Eagle on the Hill Hotel was first opened in 1853 by William Anderson, who named it Anderson Hotel. The hotel went through further name changes in 1855 to The Eagle on the Hill, then to Eagle's Nest in 1859 and back to Eagle on the Hill in 1860.
The hotel has twice been ravaged by bushfires. First in 1899; a fire destroyed all of the old hotel with the exception of two rooms. Again on Ash Wednesday (16 February 1983) the hotel suffered, with it being completely destroyed. It was rebuilt and operated with much success until its closure after the construction of the new freeway route.
