much more copper, lead, silver and gold from the ore than by other conventional methods. He experimented for some years in the laboratory, but he never improved the extraction process and was consequently demoted from his position at the mine. , there are no visible remains of the mine or the factory. Ersta Ersta is one of the many malmgårdarna (suburban manors) built in Stockholm during the 17th and 18th centuries. At these manors, wealthy, noble families from different parts of Sweden, could enjoy the same comforts as in their homes in the country. The manors were built in the suburbs, close to what constituted Stockholm in the 17th century and 18th centuries. The city has grown considerably since then, and these locations are now considered part of central Stockholm. Many of the buildings, the entire manor or part of them, are still in use and embedded in the modern cityscape. Ersta, on the high cliffs of southern Stockholm, was probably built in the 1670s by brännvin manufacturer Oluf Håkansson. At that time the land in that area was cheap since it was close to the old gallows. When the gallows were moved further away from town to make way for a new shipyard, the Stora Stads wharf, where ships for the SOIC were built, the area around Ersta became sought after and was called "a garden". The mansion passed through several owners until Jean Abraham Grill bought it in 1755. In 1770, he established a crucible steel factory at Ersta with the help of Bengt Andersson Qvist, a member of the Swedish Board of Mines. Members of the Qvist family were inspectors at the Iggesund ironworks. The steel was of good quality, but nevertheless unprofitable. In 1775, Jean Abraham sold the manor and the steel factory to Qvist who ran the company until it folded with his death in 1799. , only two of the buildings at the manor remain. They are a part of the Ersta Hospital and one of them houses the Ersta museum.
