TARGU JIU,Romania is a city located at about 300 km far from Bucharest the capital of Romania, with a population of 78,553

The city takes its name from the river Jiu, which runs through it. In antiquity, there was a Dacian village in around the location of today's city surrounded by forests. After the Roman conquests of Oltenia (101-102), military units were stationed around the roads that connected different important routes at the time. During the digging of the Targu Jiu Rovinari railroad, mosaics, coins, ceramics and Roman bricks were found in the south-eastern part of the city. This and ancient testimonies support the idea that Targu Jiu was a commercial town (a vicus) while under the Roman Empire's rule. A very important route that connects the Danube to Transylvania runs through the city, so historians believe that part of the Roman Army under Trajan's leadership stayed and then passed in the actual location of the city.

Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly.

London is a leading global city in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism, and transportation.
