In the 18th and 19th centuries it became a famous market for animals and craft products called "Eski Cuma" ("old bazaar" in Turkish). A monastical school was opened in the 18th century and a secular one, called the Slaveykov School and situated in the old Varosha Quarter was established in 1846, with Petko Slaveykov being a teacher there; a "chitalishte" was also built. Industrial development began after the Second World War. Factories producing car batteries and machines for the food industry were opened; later, furniture and textile industries developed. One of Bulgaria's largest wine production factories is located there. Targovishte is home to one of the largest glass factories in Europe. The investment in the factory was $380,000,000 and employs 1,500 people.
