Öregrund

Öregrund is a locality situated in Östhammar Municipality, Uppsala County, Sweden. As of 2010, it had 1,555 inhabitants. It is located by the Baltic Sea, on the coast of Uppland. Despite its small population, Öregrund is still commonly referred to as a city for historical reasons .

The town was granted a royal charter in 1491, by request from citizens from nearby city of Östhammar. Östhammar had once been a coastal town, but due to post-glacial rebound its harbour had become useless. The royal council granted the request to construct a city at the end of the archipelago where the sea opened. It further proclaimed "the city shall forever be known as Öregrund". The small but expanding city soon became a point of conflict. In 1520 Christian II of Denmark conquered Stockholm. A young Gustav Eriksson tried to gather an army, and Öregrund became the port whereto ships with men and weapons were transported. As a countermeasure, the Danish King had the city burnt in the winter of 1520. And so, the citizens of Öregrund had to move back to Östhammar.
