Sunda Kelapa is the old port of Jakarta, located on the estuary of the Ciliwung River. "Sunda Kalapa" is the original name, and it was the main port of the Sunda Kingdom. The port is situated in Penjaringan District, of North Jakarta, Indonesia. Today the old port only accommodates pinisi, a traditional two-masted wooden sailing ship providing inter-island freight service in the archipelago. Although it is now only a minor port, Jakarta has its origins in Sunda Kelapa and it played a significant role in the city's development. The port is currently operated by the state-owned Indonesia Port Corporations.
