This cover features a souvenir sheet jointly-issued by Austria and Slovakia on Sept.11,2009.The title is:Limes romanus & Gerulata

During the Roman period, the Limes romanus was a system of military strongholds along the Danube which protected Roman provinces against attacks of German tribes.

The left stamp "Carnuntum" shows the most significant Roman stronghold in the Pannonia province,situated next to the present-day village of Petronell in Austria.The best known Roman monument in Carnuntum is the “Heidentor” – the “Heathen Gate” built outside the town in 4 A.D. by Roman emperor Constantinus II. (337–361). Originally this gate consisted of four cross-vaulted pillars (tetrapylons), with huge columns overshadowing the emperor’s statue beneath the vault.

The right stamp "Gerulata" is the nearest Roman camp to the east from Carnuntum,in Rusovce, a part of Bratislava.This castel was built in the second half of 1 A.D. under the Flavians.The name of the stronghold Gerulata is known from a medieval copy of a Roman map of 4 A.D. – the Tabula Peutingeriana. The map shows roads in the territory of the Roman Empire from Spain to India. In the 18th century, it was bought by the Austrian prince, Eugene of Savoy, who gifted it to the imperial court library in Vienna (now the Österreichische Nationalbibliothek). The map is included in the UNESCO List of World Heritage.
