Rummu Quarry, Estonia
Rummu quarry began operation in 1938 and ceased after the fall of the Soviet Union in the 1990s. It is currently going through assessment for redevelopment. The workers were drawn from the near by Rummu Prison, which closed in 2012. Students from the Estonian Academy of the Arts have spent the last three years generating ideas and proposals for it's use - recreational centre, a composers' centre for musicians, and the most recent idea being a tech park. The land is owned by KB Auto Eesti OÜ, the CEO of which is Gunnar Bergvald, a former prison official. The latest proposal for a tech park looks likely to go ahead.
