The Archaeological Site of Volubilis was listed as a UNESCO World Heritage site in 1997.
Maroc Infini 
Volubilis was the administrative center of the province in Roman Africa called Mauretania Tingitana.
Volubilis contains essentially Roman vestiges of a fortified municipium built on a commanding site at the foot of the Jebel Zerhoun. Covering an area of 42 hectares, it is of outstanding importance demonstrating urban development and Romanisation at the frontiers of the Roman Empire and the graphic illustration of the interface between the Roman and indigenous cultures. Because of its isolation and the fact that it had not been occupied for nearly a thousand years, it presents an important level of authenticity. The archaeological vestiges of this site bear witness to several civilizations.
The site has produced a substantial amount of artistic material, including mosaics, marble and bronze statuary, and hundreds of inscriptions. This documentation and that which remains to be discovered, is representative of a creative spirit of the human beings who lived there over the ages. - in: http://whc.unesco.org/en/list/836

Some of the 1st cards in my collection are from my Sines but this is the 1st card i received from there by postcrossing. It was sent by Gracinha.

Not so long ago i've received an official card with Krakow's Barbican and for this RR, "bodexs" sent me Warsaw's Barbican. This classical Gothic structure separates the Old Town district from the New Town.
Speyer is a city of Rhineland-Palatinate, Germany. Founded by the Romans, it is one of Germany's oldest cities.

Rita "rita_simões" sent this card of the Royal Palace of Caserta, a former royal residence in Caserta, southern Italy, constructed for the Bourbon kings of Naples. It was the largest palace and one of the largest buildings erected in Europe during the 18th century. In 1997, the Palace was designated a UNESCO World Heritage Site, described in its nomination as "the swan song of the spectacular art of the Baroque, from which it adopted all the features needed to create the illusions of multidirectional space". - in: wikipedia
