The Dolder Grand in Zurich, Switzerland is re-opening after a four-year $400 million renovation. The hotel has been transformed into a five-star resort with 173 new guest rooms, a new spa, dining options and a geothermal energy concept. The new Dolder Grand was designed by London architects Foster and Partners.

The Dolder Grand has a long history. It was a health spa when it opened in 1899 and was a grand hotel for many years. The new design included restoring the hotel's main building and added two new wings, a spa and golf wing. There are also four unique suites inspired by cultural icons of the 20th century who were former Dolder Hotel: the Rolling Stones, Giulietta Masina (wife of Italian director Federico Fellini), "Maestro" Herbert von Karajan (conductor) and Alberto Giacometti (Swiss sculptor).

The spa is 43,000 square feet and has separate areas for ladies and gentlemen, an Aqua Zone with a Bisazza mosaic pool, a Snow Paradise room, workout, movement and mind-body studios, and 19 treatment rooms as well as two exclusive, over-the-top spa suites. The hotel has two new restaurants and terraces throughout The Dolder Grand offer fantastic views.

Before the construction began geothermal probes were buried under the foundation of the hotel and they draw around one million kilowatt hours of energy per year from the natural heat-storage system in the earth, reducing the energy and heating costs and consumption of the hotel. Rates start at 850 CHF per night/ double occupancy.
