Singapore is a hub for connecting flights, so for many passengers the airport is their only point of contact with the country before they're whisked away once more.
"The stunning result is a mixed-use development with gardens, attractions, retail, dining, a hotel and facilities to support airport operations", the statement describing the Jewel Changi Airport reads.
As well as an attraction for visitors to Singapore, it is also billed as a destination in its own right for local residents.
The Jewel Changi Airport is located near Singapore's Terminal 1 and it is connected to Terminals 2 and 3.
The distinctive structure, designed by Moshe Safdie, includes 40m-tall indoor waterfall and 2,500 trees in addition to the hundreds of shops and eateries - all of it linked to three Changi Airport terminals.
Come May, the Changi Experience Studio on Level 4 will bring visitors on a journey of discovery through the virtual world of Changi Airport with interactive games, projection experiences, immersive shows and gallery exhibits.
Jewel will also house the first YotelAir property in Asia.
The 1,35,000 square metre building (formerly a auto park), was designed by renowned Israeli architect Moshe Safdie.
In 2018, Changi airport served a record 65.6 million passengers, becoming the world's seventh busiest airport.
The highlight of the complex is a 40-metre indoor waterfall cascading through a steel and glass dome.
"Passengers are spending a longer time as they transit through airports, which is the reason why there is a need for us to increase the amenities", said Jayson Goh, a senior executive at Changi Airport Group.
