Béjaïa (also Bejaia) is a port city on the Gulf of Béjaïa in northern Algeria, at the foot of the Soummam valley where the Kabyle mountains meet the Mediterranean. The city has a long history as a trading port — it was here, via medieval Arab scholars, that Europe received the Hindu-Arabic numerals and the concept of zero, transmitted by the mathematician Fibonacci after his time in the city. The old city retains some Ottoman-era architecture and there are two museums: an archaeological collection covering Roman and Hafsid-period finds, and a natural history museum. The surrounding coastline has good beaches.
Gouraya National Park, on the headland immediately northwest of the city, is the main attraction for nature lovers: a limestone cape with wild beaches, Barbary macaques, and panoramic views from the Pic des Singes. The site of the Great Mosque, built during the city's peak as capital of the Hammadid dynasty in the 11th century, sits in the old town and is worth a visit for anyone interested in North Africa's medieval Islamic heritage.
