The 1967 coronation of the late King George IV of Tonga took place in the Chapel Royal. Unfortunately, the charming gothic revival structure burnt down some years ago, and so the latest coronation — that of George V — took place in the more spartan surroundings of the Centenary Church.

The Royal Chapel didn’t burn down, it was destroyed by cyclone Isaac in 1982.
