Most American leisure travelers come to Jakarta en route to somewhere else in Indonesia. The city is primarily a political center and a business destination. Situated at the northwest corner of the island of Java, Indonesia’s capital began in the 12th century as a port that served the Kingdom of Sunda. Today, it is a massive and congested metropolis. Measures are being taken to green the city and to ameliorate its chronic air pollution. Successive eras of colonial rule, from Portuguese to Dutch, have left an eclectic physical and cultural landscape. The Kota area has the highest concentration of colonial architecture. In the Old Batavia district, a restoration effort has turned a colonial Portuguese church and warehouse into living museums. But, overall, modern high-rise towers dominate the city’s skyline.
