InterContinental Shanghai Wonderland

The InterContinental Shanghai Wonderland (pinyin: Shànghǎi Zhōujì Shìmào Xiānjìng Jiǔdiàn), also known as the Tianma Pit Hotel, Shimao Quarry Hotel, Songjiang, or Pit Pegasus Hotel, is a hotel and earthscraper in Songjiang, Shanghai, China, 50 kilometres (30 miles) from city center. The hotel, which started operations on 20 November 2018, is managed by InterContinental and was built on the site of an abandoned quarry and, notably, features some rooms underwater. The design and construction process of the hotel was fraught with many delays prior to 2013. Since 2013, however, design and construction progressed at a fairly swift pace. The fit-out work was carried out in 2017, and the hotel finally opened on 20 November 2018.
