Bulgaria: Rock-Hewn Churches of Ivanovo with Postcrossing Stamp

This is the 300th UNESCO World Heritage Site in my collection. Big Thanks to everybody who helped me to achieve this aim!

Today I got two postcards: one from Bulgaria and one from Spain.

The card from Bulgaria shows a fresco from the Holy Virgin's Rock Church, one of the Rock-Hewn Churches of Ivanovo. The Rock-Hewn Churches of Ivanovo are a group of Orthodox church buildings forming a monastery complex. They are carved into stone and differ from all other monasteries in Bulgaria. The frescoes are a special feature of the complex. The Rock-Hewn Churches of Ivanovo are since 1979 on the UNESCO World Heritage List.

Stamps:

Thank You very much Christina!
