Obor stands in the place of "Târgul Moșilor", a fair famous throughout Wallachia, which was held twice a week. In old Romanian "obor" meant enclosure, corral.
Located outside the city, in the 18th century, it was also the place for public hangings. About 20 Turks captured from wars were hanged here by the Romanians
The Obor market (Piața Obor), the direct successor of the original fair, was, until 2007, Bucharest's largest public market. It covered about 16 city blocks and included a variety of indoor and outdoor market spaces, with goods ranging from compact discs to live chickens. Informally, the market spilled into the surrounding neighborhood, both in terms of street vendors and in terms of the nearby Magazin Universal ("Universal Store") named Bucur Obor, a large commercial building that has been parcelled up into hundreds of small, independent retail stores. The market was demolished, not without public outcry, in order to pave the way for a modern market and a small park, thus ending a 300 year tradition.
