University College is undergoing a $34 million dollar restoration project that aims to restore the landmark building's original beauty.
The refurbishments include state-of-the-art classrooms, a new reading garden on the east side of the building as well as all new plumbing and electrical infrastructure.
Not only will the renovations add some new aspects to the old building, but they've also kicked up some long forgotten secrets that were buried away in the 95-year-old structure.
Here are six things you may not have known.
Tower dedicated to war dead
The Middlesex Memorial Tower is probably the most recognizable part of University College. The structure was originally dedicated to the men from Middlesex County who died in the First World War.
University crests from across the globe
Each panel of stained glass that adorns Conron Hall carries a crest from a different school somewhere in the world. As part of the renovations at University College, there are plans to add light bunkers on the inside, so that the stain glass lights up at night.
Look down, waaayyy down
How many students do you think ever bothered to notice the palatial floors at University College as they went to class or ran to get to an exam on time? The type of flooring used in the building is called terrazzo, which has its origins in Renaissance Italy. It's made from chips of marble or glass embedded in cement, then polished to a shine.
Mustangs might bleed purple and white, but you might have noticed that University College seems to bleed rust. It's thanks to the original limestone, mined almost a century ago from a quarry in Kentucky. When the iron deposits in the stone come in contact with rainwater, it oxidizes. While the original quarry has long ago been exhausted, crews went to great pains to find a new source of stone for the restoration work.
The service tunnels that run beneath University College help bring light, heat and water to a number of buildings on-campus.
They run from the campus power plant near Alumni Hall to the Physics and Astronomy building and over the years maintenance crews have added hand-written signs to prevent workers from getting disoriented underground.
Raccoons, birds and high heel shoes
The renovations have uncovered some wild discoveries, including a raccoon, who had decided to take up residence in Conron Hall.
The animal was released back into the wild almost as soon as it was discovered, according to officials at Western, but it's far from the only critter who calls University College home. Crews discovered barn swallows making their home on the building's roof while doing restoration work.
One of the oddest finds though found in one of the original sections of the building's cement roof, completed in 1922.
"We've found evidence of what was going on," Fred Janzen, the restoration project manager told CBC News. "Including a ladies' shoe print that was put into the concrete back when it was wet in 1922."
"Don't know how it got there, but these are the kind of interesting things you find."
