Saint Sophia Cathedral in Polotsk | Belarus

Postcard

Polotsk is a historical city in Belarus, situated on the Dvina River. The city was a member of the Hanseatic League, an economic alliance of trading cities. 

Actually I’m not sure the city was a ‘full member’ or just had a Kontor (subsidiary trading post).
