Flying Drones at Archaeological Sites in Sri Lanka

The rules for drone flights over Sri Lanka's archaeological and heritage sites: Department of Archaeology no-objection letters, the official map and etiquette.

By the Sri Lanka Drone Editorial Team · Last reviewed 19 July 2026

Quick answer

Drone flights over archaeologically important sites in Sri Lanka require a no-objection letter from the Department of Archaeology in addition to the standard MOD security clearance and CAASL operation approval. This covers the famous heritage landmarks, including Sigiriya, Anuradhapura, Polonnaruwa, Dambulla and the Galle Fort area, and many less famous protected locations shown on the department's official map. Apply well in advance and respect on-site management rules.

The rule for heritage sites

CAASL's approval guidance is explicit: for operations over any archaeologically important site in Sri Lanka, obtain a no-objection from the Department of Archaeology, in parallel with the MOD security clearance. The department's official map is the reference for where protected sites are located, and it covers far more locations than the famous names, including monastic complexes, colonial structures and inscriptions across the island.

Applying for a heritage no-objection

Contact the Department of Archaeology in Colombo with the operation details: who is flying, the equipment, the purpose, the exact site and dates. Commercial productions should expect additional scrutiny and possible conditions on the use of footage. Allow generous lead time; the no-objection has to exist before the CAASL approval request can be complete, and heritage authorities move at institutional pace.

On-site conduct at heritage locations

A letter does not replace judgement at the site. Follow the instructions of site staff, avoid overflying visitors and ceremonies, keep distance from fragile structures, and remember that many heritage sites are also active religious places where drone noise is genuinely intrusive. Operators who treat sites respectfully keep the door open for everyone who applies after them.

Frequently asked questions

Can I fly a drone over Sigiriya?

Only with a Department of Archaeology no-objection plus the standard MOD clearance and CAASL approval. Sigiriya is among the most protected sites in the country; see the dedicated Sigiriya location guide.

How do I know if a site is archaeologically protected?

Check the Department of Archaeology's official ArcGIS map. Protection extends well beyond famous tourist landmarks.

Does a heritage no-objection allow flying by itself?

No. It is one component alongside the MOD security clearance and the CAASL operation approval. All parts must be in place.
