A Venue Like No Other
There are venues that make the iDRONE team tremble when they first hear their name. Prambanan Temple — a UNESCO World Heritage site more than 1,200 years old — is one of them. When our client gave us the brief 'exclusive private dinner in Prambanan with 500 drones', we knew this would be a show that was different from anything we had ever worked on.
Prambanan is not just about architectural beauty. This is a site with strict regulations, heritage security procedures that must be adhered to, and multi-party coordination with the management of PT TWC (Taman Wisata Candi). But that's what makes this show special.
Heritage Site Bureaucratic Navigation
Permits to operate in UNESCO heritage areas are a challenge in themselves. We start the permitting process 8 weeks before the show. Coordination involves: PT TWC as the manager, the Central Java Cultural Preservation Center, the Director General of Civil Aviation for NOTAM, and of course our own technical team.
One of the main conditions: no drones are allowed to fly beyond the height limit of the main temple structure (47 meters). This means that all drones must fly above 50 meters, which also affects the visual calculation of the viewing angle from the viewer's position on the ground.
Height and Visual Calculations
Typically for 500 drones, the operational height can vary between 40–80 meters. In Prambanan, our lower limit is 55 meters — higher than usual — so that there is a safety margin from the top of the temple tower. Our programming team had to recalculate all the formations so that they still look proportional from the viewer's position on the Prambanan page.
What's challenging: the audience faces or turns their back to the temple - meaning the background of the visual show is the temple illuminated by golden yellow heritage lights. We had to make sure the drone's LED color contrasted with the background. The final choice: a combination of bright white for the main formation, with red and gold accents for the details.
Moments That Freeze Time
When the 500 drones took off and began to form the first formation — a relief of the Ramayana in a modern light pattern — the entire audience gasped. The 200 guests from Indonesia's elite circles, many of whom have traveled the world and are accustomed to the sensation of luxury, could not hide their admiration.
The climax formation is when the drone forms the Prambanan Temple itself - the silhouette of the three main towers - right against the background of the original temple which has stood since the 9th century. Two versions of Prambanan: the one built by humans thousands of years ago, and the one built from light for 8 minutes.
It wasn't just a drone show. It is a work of art that cannot be repeated.
