Ouagadougou's primary industries are food processing and textiles. It is served by an international airport and is linked by rail to Abidjan in the Ivory Coast and, for freight only, to Kaya. There are several highways linking the city to Niamey, Niger, south to Ghana, and southwest to Ivory Coast. Ouagadougou has one of West Africa's largest markets, which burned down in 2003 and has since reopened with better facilities and improved fire-prevention measures. Other attractions include the National Museum of Burkina Faso, the Moro-Naba Palace (site of the Moro-Naba Ceremony), the National Museum of Music, and several craft markets.
