BOSTON—Celebrating its Centennial, The Fairmont Copley Plaza completed a restoration and renovation in excess of $20 million.

The project included the hotel’s 383 guestrooms and suites, Fairmont Gold, the lower lobby meeting space and the addition of a new rooftop health club and lobby lounge. In addition, OAK Long Bar + Kitchen also debuts at the hotel this summer.

“This is one of the most exciting times in the 100-year history of The Fairmont Copley Plaza,” said Paul S. Tormey, regional VP and general manager. “This investment will enhance the hotel’s preeminent position in the marketplace, while preserving much of the architectural detailing that has made the hotel a Boston landmark since its grand opening in 1912. The renovation has been thoughtfully curated to meet the needs of today’s guests while celebrating the property’s rich history and position in Boston’s Back Bay.”

The new rooms and guest corridors incorporate the marble colors and hues of the public space to bring plum and blue color schemes into the guestrooms and suites. The Fairmont Gold Lounge emulates the feeling of a Back Bay mansion with residential decor.

The hotel also introduced eight themed suites, which are mini-museums, each celebrating one of the city’s iconic institutions. Suites include the Museum of Fine Arts, Boston Pops, Boston Symphony Orchestra, The Freedom Trail, the JFK Library and Museum, Boston Public Library, The Museum of Science and The Catie Copley Suite.

The hotel’s lower lobby meeting space was renovated into a new state-of-the-art conference facility, featuring built-in A/V and technology capabilities, complemented by wood paneling. The five meeting rooms comprise 5,600 sq. ft. of function space and feature ergonomic conference chairs, new conference tables and built-in buffets.

Comprised of more than 3,000 sq. ft. the new rooftop health club features TechnoGym equipment, including cardio-vascular machines with individual entertainment systems, weight machines, free weights and benches, an expansive stretching area and resistance-training and core-strengthening equipment. Designed as a contemporary urban loft space, the health club features floor to ceiling windows with views of the Back Bay. The facility will also include an outdoor deck.

The hotel’s public areas have also received some new additions. A lobby lounge recently opened where furnishings and wall coverings are complemented by artwork, including signed lithographs by Matisse, Picasso and Chagall.

Catie Copley, the hotel’s canine ambassador, received a new custom-made dog bed as part of the renovation of the space.

In Peacock Alley, the original hand-laid mosaic tile floor from 1912 has been restored.

The Fairmont Copley Plaza is owned by Texas-based FelCor Lodging Trust, which owns interests in 82 properties with approximately 23,000 rooms in the United States and Canada.
