Visit Shanghai’s Underwater Quarry Hotel 88 Meters Deep: A 4

This video tours a hotel built inside a disused quarry in Shanghai. Once an 80-90 meter deep pit created by decades of mining, it has been transformed into a high-rise hotel with a cliff-edge glass skywalk, interconnected levels, and an underground aquarium. The project focuses on environmental transformation and architectural engineering, highlighting fire safety, waterproofing, and seismic considerations. A British design team led the transformation, turning industrial ruins into a mixed-use wonder with lush green spaces and water features. The host guides viewers through highlights including the cliff glass skywalk, the observation deck, hotel lobby, the subterranean aquarium, and the depths accessed by elevator, followed by night views of the illuminated quarry. The narration emphasizes the balance between natural ecosystems and modern luxury within this dramatic conversion.
