Royal Ontario Museum
The Royal Ontario Museum is the largest museum in Canada, featuring a wide collection of natural and cultural artifacts. It was built in 1914, and while it's still around today, it has changed significantly from its original form. Most notably, in 2007 a major renovation was completed, and the building developed the Crystal (right), a giant glass-and-steel structure that was supposed to expand floor space and introduce more natural light. Most people don't like it.1 But we're not here to focus on the crystal; we're here to focus on the exhibits that used to be at the museum before the renovation.
From visitor anecdotes and memories, the old museum was filled with the likes of taxidermy birds in old-fashioned display cases, a gallery of Canadian animals, Egyptian mummies, gems and minerals, a bat cave, a planetarium, an immersive fossil exhibit, and a dark wood room with Buddha statues designed to resemble a temple.2,5

Dinosaur Gallery
Unlike the relatively sterile and open exhibit at the ROM now, the old paleontology exhibit was dimly lit. It featured the skeletons in dioramas of their environments, with replica plants and painted backgroups.2 Other bits that people remember include miniature life dioramas, a simulated tar pit and human ancestors whose faces changed through a Pepper's ghost effect.3 Skeletons on display included:
- Albertosaurus
- Allosaurus2,4,5
- American mastodon4
- Chasmosaurus4 (right)
- Edmontosaurus4,5
- Iguanodon5
- La Brea Tar Pits fauna, including dire wolves, ground sloths, and horses
- Lambeosaurus4
- A mosasaur5
- Ornithomimus edmontonicus
- Parasaurolophus4
- A polycotylid plesiosaur. It was located in a dark corner, and lighting effects and sound effects were used to simulate being underwater.5
- Fossil rhinos4,5
- Stegosaurus4
- Stenopterygius
- Triceratops2
- Tyrannosaurus
The exhibit closed on September 2, 2005. After the renovation, most of the skeletons are still on display. But they're now separated from the environmental context conveyed through the dioramas.
Bat Cave
The Bat Cave opened in 1988. The room was a huge fiberglass cave - a replica of the St. Clair Cave in Jamaica, with the walls, scalactites, and stalagmites made from casts of the real deal.6 It featured animatronic bats, taxidermy specimens (some of which were non-bat animals, like an owl or a bobcat5), and audio of dripping water. Every so often, a flock of bats would fly overhead - using a combination of animatronics, taxidermy, and lighting effects to sell the illusion.2 People who went to it as a kid noted it was quite scary - not helped by the collection of vampire imagery at the beginnig of the exhibit.5 The original bat cave closed for renovation, but an updated version - all new cave, all new bats - opened in 2010.3
McLaughlin Planetarium
The McLaughlin Planetarium opened on October 26, 1968.
Due to provincial budget cuts, the planetarium closed on November 5, 1995. The exhibits and seating were removed and the space was used for offices and storage by the Museum. Eventually it was sold to a housing developer, and demolition began in April 2026.
