The Greek heritage of six centuries BC was discovered by archaeologists exploring the ancient Hellenic settlement of Apollonia Pontica in present-day Bulgaria.
According to the Archeology in Bulgaria news site, excavations have uncovered the well-preserved remains of a dwelling as well as artifacts including a special wine vase depicting the classical Greek myth of Odipus and the Sphinx.
The finds were made during high priority excavations near the Black Sea town of Sozopol, inside the Old Town Archaeological Reserve on the Skamni Peninsula.
The new finds were made six feet below the foundations of a 19th century house. The soil in the region has also produced more recent artefacts, such as 11th-century bone and bronze crosses.
The Skamni Peninsula is believed to have been inhabited continuously since ancient Greece.
The city was founded in the 7th century BC by Greek settlers from Miletus like Antheia. Its name was later changed to Apollonia because of its temple dedicated to Apollo with a huge statue of the god.
The colony was eventually sacked by the Romans in 72 BC who took the statue of Apollo to Rome and placed it in the Capitol.
These latest findings also follow on from other Hellenic discoveries in the region. In 2016, experts found the remains of an ancient temple dedicated to the Greek goddesses of Demeter and Persephone.
