CALMAR, or Kalmar, the capital of the above province, on Calmar Sound opposite the island of Oeland. N. Lat. 56. 40., E. Long. 16. 20. It is built on the island of Quarholm, and communicates with the suburbs on the mainland by a bridge of boats. Most of the houses are built of wood; but the cathedral, the castle, the Hôtel-de-Ville, and other public edifices, are of stone, of which there are good quarries in the island of Oeland. It has an academy, and several smaller educational establishments. The harbour is safe and commodious, but a large part of the trade has been transferred to Stockholm. It has manufactories of woollen stuffs, tobacco, and potash; and carries on an export trade in flax, timber, iron, alum, pitch, &c. Calmar was once a flourishing and strongly-fortified town; and gives name to the treaty by which Sweden, Denmark, and Norway were in 1397 erected into one kingdom under Queen Margaret. Pop. about 5500.
