Soufli is the city of silk. The silkworm breeding started from Edirne and continued around Evros river and the area of Soufli, whose inhabitants began to deal with silk as producers, workers and traders.
In the early 1880s the city became an important sericulture center. Every year, from May to June, the city pulsated to the rhythms of silk and silkworm rearing. Most part of the house of most inhabitants of the city was shaped based on the needs of sericulture. Nowadays, the silk produced in Soufli is of high quality.
