Ii Hamina is an old trading and market place

The name Hamina has its roots in the Swedish term hamn which means harbour. Inherent in the name is the fact that Hamina was originally a trading post. The exact point in time of Hamina’s genesis is not known. Literary references on the matter can be found from the end of the 14th century. Trading took place in Hamina probably as early as in the 13th century.

For a very long time, Hamina was merely a trading post. In the Middle-Ages and in the 16th century the Swedes – and occasionally traders from the East – set up their trading granaries at Hamina's upper end. Since the 17th century, trading in Hamina was dominated by the bourgeois from Oulu. At best, they had over 40 granaries in Hamina. At least one of Ii’s churches and the affiliated cemetery were located in the Hamina district in the 16th century.

Today, Hamina is a modern and tranquil residential district and event arena. Houses have been refurbished, and completely new ones have been built in place of those that were demolished. The oldest buildings – or at least the vintage of the timber used to build them – are from the early 19th century. Hamina’s public utilities were renovated during 2009 – 2011.
