Dolisie, the third-largest city in the Republic of the Congo, is located in the southwestern part of the country and serves as a key transportation and trade hub. Positioned near the Mayombe forest, it offers access to the region's dense woodlands and rich natural resources. The city has a history tied to the development of the Congo-Ocean Railway, which played a crucial role in connecting inland areas to the Atlantic coast. Today, Dolisie is a center for timber processing and commerce, while its markets and colonial-era architecture reflect its historical and economic significance.
