In a city built on small islands, one is so tiny it did not warrant being named on a Stockholm map until 1733. Seven years later, businessman Berge Ström purchased the islet. In 1750, he built a large stone house. The island was then named Strömsborg meaning Stream Castle. This double entendre refers to his last name and the Strömmen River flowing around it. In 1878, Strömsborg was made accessible by land with a small bridge named Strömsborgsbron attached to the Vasabron. Ström’s home was then replaced by the current building in 1897. Today, this is the headquarters for the International Institute for Democracy and Electoral Assistance.
