Its Jewish cemetery was established around 1900 and the last known Jewish burial was in 1970. The site is part of a municipal cemetery which is surrounded by a fence with a gate that locks. The Jewish section is 0.25 hectares in size and contains only 40-50 visible gravestones, with somewhat less than a quarter of these toppled, broken or otherwise vandalized. Some were vandalized or stolen between 1980 and 1990. The marble and granite gravestones are inscribed in Bulgarian and Hebrew. Most date from the 20th century. Overgrowth is a year-round problem but the municipality occasionally has the site cleared.

Until 1830 when the Jewish cemetery was built, Sliven Jews buried their relatives in the town of Yambol. Nearly 100 years later in Sliven live nearly 550 Jews. Two synagogues and a school are built.
