In the II century it was known as the Thracian village
Larisa. In the XIV century it was named after the patron of merchants and livestock, the medicine man
St. Vlas. He is a saint who is worshiped by the Eastern Orthodox and Catholic Churches, and in the Catholic Church he’s known by the name of St. Blajei.

In the XIV century on these lands were build 5 monasteries: “
St. Peter”, “
St. Ilia”, “
St. Andrei”, “
St. Vlas”, where the name of the present city originates from, and the woman’s convent “St. Ana”. All of them were destroyed in the XVIII century, set on fire during the many pirates’ raids, but some remnants of them still can be found. Through the years of Ottoman rule several names of this village were used, and all of them in connection with the monasteries.
After the Liberation from Turkish slavery in
1886, the name of the village was changed to
St. Vlas and is officially enlisted in the registers of the country.
