In this small African country bounded by the Atlantic Ocean, colonial fights lasted for several successive centuries, which resulted in building fortifications and strongholds in Senegal. Fortifications were built between the 16th and 19th centuries by the Portuguese, the Dutch, the English and the French. They were located mostly on the Senegalese coast and on the Gorée Island because moving inland was very dangerous for Europeans. Nowadays, many Senegalese strongholds have lost their former wonderful appearance to become only picturesque ruins. However, some of these historic buildings remained in spite of everything and today they remind us of the dark times of slave trade and the colonisation of this country. Historic buildings of this kind definitely include Fort d'Estrées situated on the Gorée Island and Fort Fedebra in Podor – the northernmost town in Senegal.
