The card shows the Kale Fotress, built in the 6th century to serve as protection but also as a nice place to observe the surroundings. In the background there's the Vodno Mountain, known for having the Millennium Cross (constructed to commemorate 2,000 years of Christianity in Macedonia and the world. The Millennium Cross is the highest structure in the Republic of Macedonia) on its top, the biggest Christian Cross on earth. On the left side of the card there's the Macedonian National Theatre.
