The BBC will have 150 cameras covering the coronation festivities, including the procession to Westminster Abbey and the ceremony itself.
Broadcasting from temporary studios in London and Windsor, the corporation will also be at the ten sites of its Lighting Up The Nation event.
There will be choreographed lasers, projections and drone displays over historic bridges and buildings, including Blackpool seafront in Lancashire, as part of the Coronation Concert.
