This cover from Poland depicts a complete set issued in 2022 on topic "Tourist places in Poland". The stamp on the top celebrates the
Old City of Zamosc, the oldest historic district of the city of Zamość. It is one of World Heritage Sites in Poland (added in 1992). According to UNESCO, this monument value lies in it being "an outstanding example of a Renaissance planned town of the late 16th century, which retains its original layout and fortifications and many buildings of particular interest, blending Italian and Central European architectural traditions.".
