Four Seasons Hotels and Resorts, together with Astir Palace Vouliagmeni SA, will spend €100m ($US119m, £88m) to transform the iconic Astir Palace into the Four Seasons Astir Palace Hotel Athens.

Due to open in early 2018, the resort will be the first Four Seasons in Greece. The 1960s hotel is undergoing extensive upgrades, with interiors by designer Meyer Davis, and, when complete, it will include 300 bedrooms and a wellness spa, fitness facilities and thermal features. Spa consultancy Blu Spas is working on the spa concept.

“The Four Seasons Astir Palace will embrace the legendary ‘good life’ of the Athens Riviera,” said Cary Collier, principal at Blu Spas. “The wellness spa, fitness, thermal features and pools all offer indoor as well as coastal and beach experiences for guests and locals that are inspired by the region’s rich history.”

The Astir Palace also includes a 30-hectare (75-acre) peninsula with pine-dotted, scenic landscaped gardens as well as upscale retail and dining options and high-end seafront residences.

The hotel’s complete renovation will also include a significant upgrade of Astir Marina, the advancement of Astir Beach, the development of up to 13 high-end residences, and the creation of a Peninsula Park.

“Born in the 1960s, this location became a legendary and savoured international playground,” said Collier. “With the Aegean Sea at your feet, the city of Athens at your back, and the sun on your shoulders in Greece, this is one of the most magical places on the planet.”
