Ansgar monument

The Ansgar monument is a stone memorial on Björkö island with a large granite cross structure positioned on an elevated point. From this location, it overlooks the surrounding Baltic waters and the site of the former Viking settlement of Birka.

The stone was erected in 1834 to mark the place where Archbishop Ansgar carried out his first Christian mission to Sweden around the year 829. The monument stands on the grounds of an ancient fortress that had served as a major trading center since the 8th century.

This monument marks where Christianity first took root in Sweden, standing at a place that holds deep meaning for the country's religious transformation. Visitors can sense the meeting point between the Viking past and the arrival of new spiritual traditions.

The monument is reachable via marked paths from the nearby Birka Museum, and regular boat services operate from Stockholm to the island during summer months. The site is best visited in fair weather to fully enjoy the views from the elevated location.

The memorial stone was placed at a location once home to Birka, one of the most important early northern trading hubs. Beneath the modern monument lie traces of a world that flourished long before the Christian era.
