In 2020, the old city of Luxembourg and its fortifications have been listed as UNESCO World Heritage for 25 years. The seventh edition of "Dat ass Lëtzebuerg!" is therefore dedicated to the cultural heritage of the capital. In addition to a detailed description of the architectural treasures of the capital embellished with many photos, the book contains 14 mint stamps that document the various stages of the circuit in a philatelic manner.
THIS EDITION IS PART OF THE OFFICIAL PROGRAM „ 25 YEARS LËTZEBUERG PATRIMOINE MONDIAL”.
