Samudraraksa Museum sits within the Borobudur visitor area and tells the story of a reconstructed Indonesian outrigger ship that sailed from Java toward Africa. The museum uses the voyage to explore ancient maritime trade, shipbuilding, and Indonesia's links across the Indian Ocean.
It is a useful add-on after the temple rather than a separate destination. The subject broadens Borobudur's story beyond stone reliefs, reminding visitors that Java's old world was connected by sea as well as by kingdoms and pilgrimage routes.
