Linggam Cahaya Museum on Daik Island has been operating since 2003 in Lingga Regency, Riau Islands. The museum displays approximately seven thousand items that include ceramological, ethnographic and numismatic collections.
One of the most interesting collections is the regional currency known as Soekarno Riau Islands (SKR). This artefact has become an important part of the documentation of the region's history.
