Sixteen of its eighteen floors sit below ground, carved into the cliff wall of a flooded quarry pit — and two of those floors are actually underwater, with suites that look straight into a saltwater aquarium.
The quarry had sat abandoned since 2000 after decades of mining — Shimao Group spent over a decade and $300 million transforming the 88-metre-deep pit into a functioning 5-star hotel, opening in November 2018.
Only two of the hotel's 18 floors sit above ground; the remaining 16 descend down the quarry wall, a design sometimes called an "earthscraper" — the inverse of a conventional tower.
The bottom two floors sit inside a submerged saltwater aquarium roughly 10 metres deep — six underwater suites and a seafood restaurant called Mr. Fisher look directly into water filled with real fish.

Building in a flooded pit meant patenting new methods just to stop concrete separating on the way down and to prevent landslides.
The hotel sits in Songjiang District, roughly 30-50km from downtown Shanghai — a deliberate day-trip or overnight destination, not a city-center stay.
Guests can bungee jump, rock climb the quarry wall, or kayak across the lake — the pit itself is part of the attraction, not just the building.
Three ways to plan a visit around the underwater rooms and the quarry.
The six underwater suites are the hotel's signature rooms and the most sought-after — reserve as early as possible.
Some tours and day passes allow visitors to see the quarry and public areas without booking a full overnight stay.
Shanghai Hongqiao Airport connects to Songjiang District by car in roughly 45-60 minutes.
Given the aquarium-adjacent suites and pool access, worth packing even for a short stay.
