A few days ago i've arranged a trade with a girl from Russia for a card from Yaroslavl, a Unesco whs missing in my collection. On the same day i send my card to that girl, i've received Sarah's envelope with this card showing the belfry of the Church of the Savior Monastery in Yaroslavl.
"This monastery constructed in 1506—1516 on the foundations of the original edifice dating back to 1216—1224. In the 16th century, the first stone wall is built around the monastery. It is from this monastery that an army of volunteers led by Minin and Prince Pozharsky set out to liberate Moscow from Polish invaders. In 1787, the monastery was closed and converted into a residence of the Yaroslavl and Rostov bishops." - in: wikipedia
This is also a card from a russian unesco site, Kolomenskoye. On the card there's the Water Tower from the 2nd half of the 17th century and the Bell Tower of St. George from the 1st half of the 16th century.
And now a card from Skopje, Macedonia's capital city, showing a street in the old town.
Skopje's "Old Town is situated in an area between the Stone Bridge and the Bit Bazaar, and between the Kale fortress and the Vardar River. In the past all economic activities in the city were taking place in this part of it. In the period between the 16th and 17th centuries, the Old Town reached its urban and economic zenith, developing into one of the largest and most significant oriental old bazaars in the Balkans. It is full of bustling shops that beckon visitors. This bazaar is an interesting mixture of Eastern and Western culture. Although Islamic architecture is predominant in the bazaar, there are several churches as well." - in: wikipedia
