It is also the capital of Kalmar County, which comprises 12 municipalities with a total of 233,776 inhabitants. From the thirteenth to the seventeenth centuries, Kalmar was one of Sweden's most important cities.
Between 1602 and 1913 it was the episcopal see of Kalmar Diocese, with a bishop, and the Kalmar Cathedral from 1702 is still a fine example of classicistic architecture. It became a fortified city, with the still mighty Kalmar Castle as the center. After the Treaty of Roskilde 1658 Kalmar's importance diminished, until the industry sector was initiated in the 19th century. The city is home to parts of Linnaeus University.
