This enormous, gold-plated Tibetan prayer wheel is turned with the aid of rushing water from the Yellow River (along with some elbow grease). The prayer wheel is 27m tall, 10m in diameter and weighs 200 tonnes, earning it a spot in the Guinness World Records as the world’s largest prayer wheel.
Inside the wheel are 200 copies of the Kangyur text, and the base contains a large prayer hall. Near the wheel is a museum of Tibetan artefacts.
The wheel is located in a dedicated park along the Yellow River, which can be reached on foot by following Huanghe Nanlu behind Yùhuáng Pavilion and turning left at the large suspension bridge (itself a great spot for catching sunset over the river). You can rent bikes in the old town or at the start of Nanbinhe Lu (from ¥15 per hour) to cycle along the Yellow River.
