The city of Rummu, which is in northern Estonia, dates back three centuries. First to settle in the region were the Teutonic Knights, who founded a castle and monasonline slots reviewtery under the Livonian Order. With a prison complex & a limestone quarry, Rummu grew into a major industrial hub over time. Convicted criminals & political prisoners were housed in Rummu Prison during the 1940s Soviet construction, and they were made to labor in the adjacent quarry, which grew to be one of Estonia's biggest.
