The landmark building, which dates back to 1787, lit up in the colours of the Union flag to celebrate the crowning of King Charles.
The lights changed from the standard purple and white shortly after 9pm on Saturday, and attracted dozens of intrigued passersby to take pictures of the illuminated spectacle.

“The King’s Coronation will not only mark a special, historic occasion and a chance for people to get together in celebration – it’s also an opportunity for the city to showcase its musical and artistic talents and for people to enjoy and learn more about their local community.”
