Located around a 20 minute drive west of Lisbon, the property is set within the Quinta da Marinha Original estate and is surrounded by sand dunes and pine trees.

Drawing inspiration from the ocean in both its design and menu, The Oitavos spa has a contemporary design that features sleek lines and panoramic windows intended to focus attention outwards to its dramatic natural surroundings.

Facilities include 10 treatment rooms, an indoor and outdoor seawater pool, plus a sauna, steamroom and whirlpool. There will also be a spa garden area for guests to be able to practice yoga in a private cabana.

The ocean theme will carry through to the treatments, which will include sea salt exfoliations and scrubs, a seaweed and algae wrap and a range of anti-ageing therapies. The spa will exclusively use organic spa brand, Voya.

Stephen Roughley, General Manager of The Oitavos said: "We are delighted to finally be able to share The Oitavos with the public. The hotel is the culmination of the Champalimaud family's vision, having first purchased the land during the 1920s, and completes this exceptional estate."

The estate also offers range of sports options including an equestrian centre, a health and rackets club and the Oitavos Dunes golf course. Details: theoitavos.com
