Overview of Sao Tome and Principe (note on "Java")
São Tomé and Príncipe is an island country in west-central Africa, consisting of the islands of São Tomé and Príncipe and the surrounding islets, with the capital, São Tomé, located in the northeastern part of São Tomé. Located on the Gulf of Guinea, about 200 kilometers from the African continent, the country was colonized by Portugal in the 15th century and became independent in 1975, with Portuguese as the official language and an economy based on agriculture (cocoa, palm oil) and tourism. It should be noted that "Java" is not a city or region of the country; Java is the main island of Indonesia, with cities such as Jakarta and Surabaya, and has nothing to do with São Tomé and Príncipe, possibly due to a confusion of names.

Kostolac, Serbia: City of Energy and Meeting Point of History
Kostolac is an industrial city in the eastern Serbian state of Pomoravlje, situated on the banks of the South Morava River, about 80 kilometers east of the capital Belgrade. As an important energy hub for Serbia, it is known for its lignite mining and the Kostolac power station, which supports the country's electricity supply. The city's surroundings are a mix of natural and human landscapes: the floodplain of the South Morava River creates fertile farmland, while the nearby "Kostolac Archaeological Park" harbors remains from the Roman period, including ancient tombs and pottery shards, which tell the story of a life lived 2,000 years ago. Despite its industrial labeling, Kostolac maintains a quiet, small-town atmosphere and serves as a window into the energy, history and culture of eastern Serbia.
