5 secrets of Parliament Hill

More than 325,000 people tour Parliament Hill in Ottawa every year, but most don't get to go behind the scenes in one of the country's most important buildings.From secret doors to the Speaker's Scotch, CBC News offers upninethings you probably don't know about Parliament Hill in a two-part series.

1. One man controls time on Parliament Hill

Public Works employee Robert Labontis responsible for many of the most prominent elements on Parliament Hill, but the most visible may be the Peace Tower clock.

Controlled from a small room inside the tower, Labontsets the big clock using a pilot clock that simulates the same time. The pilot clock is locked, with only three or four people holding a key for it, he said.

"I can tell from here what the Peace Tower clock is reading.I can move them at the same time. So when I change the hour, Im actually looking at this and not outside," he told CBC News.

Public Works sets the clock by the National Research Council official Canadian timeand, twice a year, it'sLabont's job to change the time.

Because the clock was built in 1927, the mechanism won't allow it to turn backwards. So, when most other Canadians turn their clocks back an hour in thefall,Labontgoes in at 2 a.m., stops the Peace Tower clock for an hour, re-sets other clocks around Parliament Hill, and starts up the Peace Tower clock when 2 a.m. hits for the second time.

"It is 1927 design. We cant turn back time. We can stop it, but we cant go back in time. So youll never see the dials go backwards," he said.

2. The flame in the middle of the lawn isn't eternal but coins thrown into the fountain fund research

Many people refer to the Centennial Flame as an eternal flame but the flame is turned off four times a year for a thorough cleaning of the fountain.

Public Works employees every week collect the coins thrown into the fountain around the flame, and the House of Commons human resources committee uses the $4,000 to $5,000 collected every year to fund research into disabilities.

The 2013 award, according to the parliamentary website, went toSara Carleton for her research looking at Olympian Clara Hughes and how she has affected the way Canadians think about mental health disorders. Hughes helps to raiseawareness about depression.

3. There's a secret door in Tom Mulcair's office

The leader of the Official Opposition gets an elaborate office on the fourth floor of Centre Block, just above the Prime Minister's Office, that includes a fireplace and detailed frescoes depicting soldiers in battle.

The office also has what may be Centre Block's only secret door.

Identical wood panels decorate the wall on either side of the fireplace, but one actually sits on hidden hinges.

"This panel on this side here," Mulcair told CBC News, pointing to the panel to the left of the fireplace, "is actually a secret door."

The door opens into the next office, occupied by Mulcair's executive assistant, George Smith.

"The legend is that [former prime minister William Lyon]Mackenzie King,especially in the daywhen there wasnt a lot of security, people used to just wander in and when there were people out there he didnt want to see, there was another door and he could sneak out the back way," Mulcair said.

4. Animalsabound in Centre Block

While Centre Block is a Gothicbuilding, House curator David Monaghan says that style of architecture can be light and whimsical as well as dark.

"The selection of subjects inthe building, for a Parliament, is not alwayspolitical," he said in the building's mainhall, known asthe rotunda orConfederation Hall.

"A recurring theme in the building isCanadian flora andfauna. You see pictures of owls and snow geese and fish. It'snot exactly terribly serious when you think about it:thatyou havea place where kings and prime ministers walk through [and it]is adorned with fish andfowl," Monaghansaid, pointing out that the animals, including beavers and bears, are evenfrolicking.

The main entrance, one floor above the visitor entrance and used by parliamentary staff and journalists, is filled with architectural detail. One Monaghan loves to point out starts from the central column in the hall.

Green and white marble are arranged as a compass rose (the design on the compass face), with a wavy green stripcirclingthe rotunda. A straight green circle encompasses the wavy one.

"When you look at it, it's just a lovely pattern and most individuals don'trealize much about it," Monaghan said.

"The wavy linerepresents the ocean on the floor. The circle represents the earth ... [Parliament]'sthe point at which we find direction, not only in the building but also for thecountry," he said.

It fits with the architect's idea of Parliament as the ship of state, he added. The floors in the offices of the House and Senate speakers, the prime minister, the Official Opposition leader and the House of Commons all have teak floors with ebony inlay, copying the teak used on great ships.

The ebony represents the tar that would have been used to seal a ship's floor, Mulcair told CBC News from inside his fourth-floor office.

5. An enormous portrait of Sir John A. Macdonaldhangs in thePMO

Prime Minister Stephen Harper's office has little other than some chairs and an imposing desk, leaving one item to dominate the decor: a portrait of Sir John A. Macdonald, Canada's first prime minister a Conservative.

When Google Streetviewwas allowed into Harper's office, it was just as tidy as when press secretary Carl Valle showed CBC News around. A Beatles mug sits on the desk and photos of Harper with his family hang on the wall that would be to hisright when he's seated at the desk.

The office waskept by Conservative leaders from 1924 until 1963, lending it special meaning to Harper, Valle said.

"Hes personalized it," Vallesaid, pointing to therow of family photos along one wall.

"But it speaks to the history of Parliament. So he comes in and he can appreciate where he works. And this is the mandate that he received from Canadians, [so] he can come here and work hard for them. And it serves as a great reminder of the privilege and the honour that he has to work here."

In a statement, Harper said Centre Block is an important part of Canada's rich history.

"From official visits to daily parliamentary duties, my office reminds me of the effort and dedication of all those who have walked the halls of Parliament Hill before me and who have contributed to making Canada into the strong, beautiful country we know today," Harper said.
