In the chaotic final days of World War II, as Allied forces closed in, a covert Nazi escape network known as the ratline operated from the Black Sea port of Constanța
You are a Roman imperial archivist on a secret mission in 1st century AD Dobroudja, tasked with a critical recovery.
You arrive in Constanța, heir to ancient Tomis, to
Follow in Ovid's footsteps during his exile in Tomis, from the Belle Époque Casino to the Roman remains of the oldest port city on the Black Sea.
Constanța immediately reveals its Belle Époque face at the 1910 Cazinoul, built under King Carol I's reign with its emblematic facade featuring towers and balconies. This building with 500-person capacity, witness to 20th-century political transformations, has hosted since Romanian royal times the cultural events that shaped this port city's identity. Your investigation begins here, where Art Nouveau inscriptions might hide the first clues to Ovid's lost register.
The Farul Genovez, built in the 14th century by Genoese merchants, rises 40 meters high as one of Constanța's oldest structures. This stone tower, restored in the 19th century under Carol I, served as a maritime landmark since the Middle Ages and symbolizes the port city's commercial continuity. Genoese traders may have consulted the Latin poet's writings here, transforming this lighthouse into a secret library of late Antiquity.
The Moscheea Carol I, built in 1910 in neo-Moorish architecture, testifies to post-Ottoman Constanța's religious diversity. This unique historical mosque of the city, restored in the 20th century with preserved period mosaics, recalls centuries of Turkish domination over this Pontic coast. In its archives might hide Arabic translations of Ovid's Metamorphoses, transmitted by Constantinople scholars.
At the heart of Piața Ovidiu, the Statuia lui Ovidiu erected in 1887 by Ettore Ferrari rises 3.5 meters in white marble. This work commemorates the Roman poet's exile in Tomis from 8 to 17 AD, with its Latin inscription recalling the link between ancient literature and modern city. The Muzeul de Istorie Națională și Arheologie, founded in 1878 in a neoclassical building, preserves over 100,000 catalogued pieces from Roman and Ottoman periods, including mosaics and sculptures from ancient Tomis.
Your journey ends at Portul Constanța, one of the oldest Black Sea ports with Greek and Roman origins. This strategic infrastructure of both world wars contains underwater archaeological remains and 19th-century structures. The paved alleys of the Old Port, witnesses to international trade since Antiquity, reveal their final secrets: you leave with the certainty that Ovid bequeathed to Constanța much more than his nostalgic verses, but a maritime identity forged between East and West.
