China's newest luxury hotel lies deep underground.
An 18-story resort is expected to open this month in an abandoned 88-meter (289-foot) quarry in Shanghai after nearly a decade of construction.
According to the plan, guests could check in the InterContinental Shanghai Wonderland worth £ 225m from 15 November, a hotel spokesperson told MailOnline.
The room rate starts at 3,325 yuan (£ 371) on the official booking app.

The five-star InterContinental Shanghai Wonderland has cost around £ 225 million
The stunning "Groundscrapper" is two stories above the ground and 16 stories below the ground
The extraordinary hotel lies like a sparkling waterfall in the rocky pit, two stories above the ground and 16 stories below.
The lowest floor is almost 700 meters below the top floor of the J Hotel, which is said to be the tallest hotel in the world and is also under construction in Shanghai.
Even more amazing is that the two deepest levels of the 336-room hotel are immersed in an artificial pond – a proud feature for hotel developer Shanghai Shimao Group.
The hotel has an underwater restaurant. In the future, guests to the Presidential Suite could watch underwater fish shoals through a 15 meter wide glass window.
Adventure sports facilities including climbing walls and trampoline are expected to be added, as well as a theme park and glass-bottomed bridge.

The idea of the hotel was suggested by Xu Rongmao, chairman of the Shanghai Shimao Group, who had been to many "crazy" hotels and wanted to build an even crazier hotel in Shanghai
In a city known for its gleaming skyscrapers, the quarry hotel becomes a unique "groundscrapper", a building that is built down into the ground rather than up toward the sky.
The spectacular five-star hotel, referred to by locals as the "Deep Pit Hotel", is located at the foot of Tianma Mountain in Shanghai. The quarry in which he is located was first excavated in the 1950s and abandoned in 2000.
The idea to build a high-end resort there was proposed in 2006 by Xu Rongmao, chairman of the Shanghai Shimao Group.
After visiting the dilapidated quarry, Mr. Xu, who had been in many "crazy" hotels around the world, wondered if he could build a crazier one in the open pit.
"[I] "I want to turn the city's scar into a treasure," Mr. Xu said in Shanghai last year in Jiemian News.
The architects of the building from a British company used nature in the design process
Planned are an artificial waterfall, a glass bottom and adventure sports facilities
Shimao bought the land in 2006 and the land was broken in 2009.
After nine years and two billion yuan (£ 225 million), Mr. Xu's dream has finally come true.
For the architects of London-based Atkins, it is a pioneering experience to design a building that is essentially upside down.
The unusual settings of the hotel allow the team to design eco-friendly features. One of them is the ventilation of the hotel.
The lowest level of the quarry hotel is almost 700 meters below the top floor of the highest hotel in the world, the J Hotel, which is currently located in the Shanghai Tower (right).
As there is a pond down in the quarry, the air outside the hotel is cooled by the water.
Therefore, architects have made it possible for the cooler air in the lower floors to be sucked into the building. As the air in the building heats up by people and equipment, it becomes warmer and rises through the building to drain on the top floor above the floor, creating a natural airflow.
On the other hand, a part of the rock wall lies inside the building and provides an ideal thermal mass to regulate the temperature of the building.
InterContinental Hotels Group has not posted any pictures of InterContinental Shanghai Wonderland yet.
From 15 November, guests can now book Alitrip on the Chinese travel site. The prices for the rooms are between 1,488 yuan (£ 168) and 2,888 yuan (£ 326) per night.
The InterContinental Hotels Group's official booking app can book rooms from December 1st at a starting price of 3,325 yuan (£ 371).
