The Ngadjuri people are the traditional owners of the land in Clare Valley. At the Red Banks Conservation Park near Burra, the new generation of Ngadjuri and archaeologists uncovered a burial ground of the Ngadjuri people. The uncovering of this burial ground enables the Ngadjuri people to connect with their ancestors. At Red Banks Conservation Park, as well, the remains of 120-kilogram marsupial lion, diprotodon or giant wombat, echidnas and euros (an extinct mega fauna) were uncovered. In early 1840s, the Irish began to settle in Clare Valley. The valley's first courthouse and first police station, built in 1850, are preserved to date by the National Trust of Australia. The discovery of copper in early 1800s gave rise to the establishment of Burra Monster Mine, the world's largest mine in 1845. Because of copper mining, thousands of migrants flocked to Clare Valley. Remnants of this copper mine still stand today. In 1851, the Jesuit Priests at Sevenhill Cellars started wine production. To date, the Jesuits carry on to make sacramental wine, making Sevenhill Cellars the oldest winery in Clare Valley. The copper mining boom in the 19th century gave rise to Clare Valley's extravagant mansions. Wealthy mine owners built a number of these mansions in Clare Valley. One of these mansions is the Martindale Hall—a hall built in 1879. The Bundaleer Homestead, the last of Clare Valley's pastoral homesteads, was built in 1901. One hundred years later, a painstaking and extravagant restoration was made on the Bundaleer Homestead. Nowadays, wine-making and agriculture are the centerpieces of Clare Valley's economy. The wine-making industry of this valley is complemented by quality restaurants, pubs, cafes, heritage landmarks, bed and breakfasts accommodations. Objects of the pioneering days of wine-making and agriculture are displayed at the Roseworthy Musuem and Annie's Lane Museum.
