It is the second largest dome church in the world and the first cathedral in Britain. It was here that Princess Diana married Prince Charles in 1981. The interior of the church is decorated with beautiful reliefs and exquisite murals, with tall pillars, which is magnificent and magnificent. Dozens of rows of connected seats are neatly arranged, full of holy and solemn atmosphere. Note that photography is not allowed inside. The cathedral is basically divided into three parts: the central hall on the ground, the underground tomb and the viewing platform on the top, which overlooks London, and can also enjoy English afternoon tea in the cafe of the viewing platform.
