Mas River

During the times of the Dutch East Indies, this river was heavily utilized as a goods transport route.

Due to its long history serving as a major transport route, many historical buildings can be found along the river bank.

These include the Kali Mas harbour, old settlements and trading houses along the river banks, as well as the residence of the governor.

There is also a collection of old bridges, including the famous historical landmark Jembatan Merah (Roode Brug), as well as a drawbridge (which is no longer operating).

With a budget of 9 Billion Rupiah (approximately US 1 million), 9 areas along the river banks are planned to be revitalized starting from 2008.
