The US$4.2bn (€3.7, £3.2bn) Wynn Palace has opened in Cotai, Macau, with a 4,497sq m (48,403sq ft) room spa – one of Macau’s largest.

Designed by TAL Studio and inspired by the royal residences of China’s most fabled dynasties, the 22-treatment-room spa is designed to honour the grandeur of the imperial court.

Guests arrive at the Grand Court, where a solid brass Foucault pendulum is suspended in the air, its rhythmic swaying designed to mark the entrance into the tranquil spa landscape.

A hand-painted, sepia-toned wall mural runs the length of the promenade, depicting a scene of the life around a Chinese palace and the surrounding waterways.

The spa includes 18 single treatment rooms, of which six are VIP suites, and four double treatment rooms, two of which are VIP suites – all named after gemstones. The VIP suites feature hand-made wallcoverings, daybeds for relaxing, soaking tubs and a water therapy zone surrounded by stone.

Separate men’s and women’s facilities feature water airbeds, whirlpools, cold plunge pools, saunas, steam rooms, experience showers and heated tepidariums.

Signature treatments include the Royal Enchantment four-hand massage and the Diamond Life Infusion facial, which combines a gold bar, light therapy and a gold soft mask.

Before or after treatments, guests can enjoy services such as light therapy masks, oxygen therapy, a cologne and perfume bar, and complementary foot, neck and scalp massages.

The spa also includes an outdoor swimming pool and spa pool with a cafe offering healthy cuisine. A fitness centre includes advanced Cybex equipment as well as a yoga room and personal trainers, and a salon offers professional hair, nail and beauty services.

The hotel itself boasts 1,706 bedrooms, and features an eight-acre Performance Lake and fountain show, which employs 1,196 water jets that perform intricately choreographed musical fountain shows. Guests can view the fountains shows and enter the resort through a ride in a Sky Cab, which travels more than 90ft above Performance Lake.

The resort also is home to thousands of works of fine and decorative art, representing an investment in excess of US$125m (€110m, £95m).

“Wynn Palace is arguably the most beautiful hotel in the world, which is a wonderful thing to be able to say,” said Steve Wynn, chairman of the board and CEO of Wynn Resorts.
