Accra was founded by the Ga people in the late 1600s. The word Accra comes from the word "Nkran" meaning ants. This is because of the many anthills seen in the countryside around Accra. During part of its history, Accra was a very important place for trade with the Portuguese. The Portuguese built a fort in the town. Many other countries also built forts at Accra during the 17th century. These countries included Sweden, the Netherlands, France, the United Kingdom and Denmark.
