Republic of Sierra Leone
   Sierra Leone is located in the western part of Africa and of the Gulf of Guinea (Atlantic Ocean), northwest of Liberia; the territory is flat along the coastal strip, but gradually rises towards the inland until it reaches almost 2,000 meters; Sierra Leone is one of the poorest countries in the world and the civil war at the end of the last millennium has exacerbated the difficulties for the local population.

   Sierra Leone is administratively divided into 4 provinces, which have the names of the cardinal points; the northern province constitutes half of the territory and is also the most populated, while the western province is mainly occupied by the capital and a few adjacent rural areas.

   There are not many important cities in the country, with the capital having more than one million inhabitants and another 4 inhabited centers over one hundred thousand people; however, each of the 4 provinces has at least one relevant city.
