The Fairmont Royal York Hotel opened on June 11, 1929. A former railway hotel, The Royal York was built by the Canadian Pacific Railway, and is located directly across Front Street from Union Station. It can be accessed from the station both at street level and underground via the PATH. (PATH is a 29-kilometre (18 mi) network of pedestrian tunnels beneath the office towers of Downtown Toronto. According to Guinness World Records, PATH is the largest underground shopping complex in the world with 371,600 square meters (4,000,000 sq ft) of retail space.)The 28 floor tall Chateau-style building was the tallest building in Toronto when it was built, and the tallest building in the British Empire until 1945. The hotel was enlarged in 1956-57 with the addition of the east wing to a total of 1,365 rooms and was the largest hotel in the Commonwealth for many years, and is still the second largest in Canada. The Fairmont Royal York has been the residence of choice for Queen Elizabeth II and other members of the Royal Family when they visit Toronto. The Queen usually has an entire floor reserved for her and her party, occupying the Royal Suite herself.The Royal York has a terrace garden on the 13th floor, which provides its nine restaurants with fresh herbs, vegetables and flowers. In July 2008, the Royal York installed three beehives on its rooftop terrace. Three queens and their 40,000 workers provide the chefs with up to 700 pounds of honey. The hotel named the hives the Honey Moon Suite, the Royal Sweet and the V.I. Bee Suite.
