rights were restricted to previously mined areas; this coupled with further restrictions imposed by the National Parks and Wildlife Service Act (1972) make it unlikely that mining will occur in the future. Klopper's quarries Klopper's quarries, in the park's south, were mined in the late 19th and early 20th centuries. They were established by Heinrich Kloepper—later anglicised to Henry Klopper—who arrived at Adelaide in 1847 from Hamburg, Germany. He purchased land in Hope Valley and a section below Anstey Hill. On the Anstey Hill section he opened his first quarry in 1850. The Klopper quarries supplied aggregate for road building and bluestone for home and road kerbs. After Klopper's death in 1888 his wife and sons continued the quarries' operation. Stone from the first quarry was used to build a family home, on the south east corner of nearby Valley and Grand Junction roads. Additional quarries were opened and supplied metal for most of the roads constructed in Highercombe. In 1905 the family opened a freestone quarry within the park that operated until its 1927 sale. The freestone quarry was used to host plays as part of the Adelaide Festival of Arts. It seated about 800 people and its face provided a backdrop to the performances. Three plays were performed over fifteen nights in the 1980 festival. A nine-hour production of the Mahābhārata, by the theatre company of Peter Brook, was performed in 1988. Ellis Cottage and Rumps Bakery The historic Ellis Cottage and Rumps Bakery buildings lie near the corner of Perseverance and North East roads. Built in 1854, Ellis Cottage is a single room stone building built by John Stevens, founder of Steventon Estate that later become the suburb of Tea Tree Gully. It was named after the Ellis family, who owned and used the building for storage for many years until World War II. Rumps Bakery was built in 1854 with local stone. From 1867 to 1893 it was rented to Charles Rumps, who started Tea Tree Gully's first bakery in the building in 1872. In 1894, the building was sold to Ernest Heitmann, who continued to use it as a bakery. Until the mid-20th century, the Ellis family and an adjacent general store frequently used it for storage. Assisted by a government grant and supervised by the Department of Environment and Heritage, the Friends of Anstey Hill stabilised both buildings in 2000. Water filtration plant In
