Luoyang has been a capital for longer than almost anywhere in China — thirteen dynasties over some 1,500 years, starting with the Eastern Zhou and running through the Eastern Han, the Northern Wei and the Tang. It sits in western Henan on the middle reaches of the Yellow River, in the heart of the Heluo region that Chinese tradition calls the birthplace of the nation. The old saying 'everything under heaven lies at its centre' was written about this patch of ground.
The city wears that history lightly, mostly underground. The Longmen Grottoes are the reason most visitors come: two hills facing each other across the Yi River, carved over 400 years from the Northern Wei into the Tang, with about 100,000 statues in 2,300 caves and niches. The great Vairocana Buddha at Fengxian Temple is the one everyone photographs — a serene, faintly feminine face that legend says was modelled on Empress Wu Zetian.
Beyond the caves, Luoyang is a city of firsts and rituals. The White Horse Temple is where Buddhism is said to have entered China, named for the horses that carried the scriptures. The Luoyang Water Banquet is a 24-dish feast that arrives in waves, each dish swimming in broth. And every April the whole city turns over to the peony, its 'king of flowers', with parks and roadside beds blazing yellow, pink and purple.
