Stepping away from the garden into the shade of the many trees around Rideau Hall, one notices many of them have plaques beneath them, with the names of presidents, world leaders, and royalty. A plaque here shows the reason- many of these trees are the result of ceremonial plantings that continue to this day. It doesn't take long to find trees planted by Queen Elizabeth, Nelson Mandela, Mikhail Gorbachev, Dwight Eisenhower, Queen Beatrix, Queen Juliana, Harry Truman, Lech Walesa, and many other dignitaries. When John and Jackie Kennedy did this in 1961, JFK messed up his back, a perennial problem for the president.
Nearby we get our first view of Rideau Hall. The mansion first built by McKay has been expanded through the decades since, and draws the visitor in. The mansion at present consists of 175 rooms across some 9500 square metres (over 100 000 square feet) of space, with numerous additional buildings on the property. Most of the Hall is used for official business, with a relatively small portion of it as residence for the governor general's family.
The Ceremonial Guard are on sentry duty here during the summer, and their officers are on hand when a tourist would like to pose for a shot.
The Hall itself is a marvel to behold, a mixture of architectural styles- Regency, Norman, and Florentine.
