The origins of Sandi Museum trace back to 2006, when Sri Sultan Hamengku Buwono X and Major General TNI Nachrowi Ramli initiated the project to preserve Indonesia’s cryptographic heritage. Their founding vision was to create a space where visitors could investigate the secret world of codes and ciphers that played a vital role in the nation’s struggle for independence.

The path to establishing this unique museum faced significant challenges. The 2006 Yogyakarta earthquake disrupted the plans, delaying construction and renovation efforts. Like a coded message, the museum’s future remained hidden, not lost. On July 29, 2008, Sandi Museum finally opened its doors to the public, first at the Museum of Yogyakarta Struggle.

In 2014, the museum found its permanent home in a building of great historical significance. Visitors now find it housed in a Dutch colonial structure that once served as the Ministry of Foreign Affairs. This location adds another layer of intrigue to the experience, as guests are surrounded by walls that have witnessed the evolution of Indonesia’s diplomatic and cryptographic history.

Within these walls, visitors can uncover the secrets that shaped the nation’s past and continue to influence its future.
