This week i'm done with unesco cards, next week should arrive more.
This one, Birka and Hovgården, was sent from Sweden by Merja "merjade". Most of my swedish unesco cards have been sent by Merja.
"The Birka archaeological site is located on Björkö Island in Lake Mälar and was occupied in the 9th and 10th centuries. Hovgården is situated on the neighbouring island of Adelsö. Together, they make up an archaeological complex which illustrates the elaborate trading networks of Viking-Age Europe and their influence on the subsequent history of Scandinavia.
Birka was also important as the site of the first Christian congregation in Sweden, founded in 831 by St Ansgar." - in: http://whc.unesco.org/en/list/555The Ansgar Chapel was built 1000 years after Ansgar's, a german missionary, arrival in Birka.
