Peerless Planetarium

The history of the modern planetarium in Canada goes back farther than we may be aware. Until the early 20th century the word 'planetarium' could be understood to mean several different types of instruments, that we might now recognize as orreries, planispheres, astronomical clocks, etc. One such was Wyld's Globe, a hollow sphere more than 18 metres wide. This functioned as an inverted globe of the Earth with geographical features modelled on the inside in plaster of Paris, with a scaffolding for paying visitors to climb up and study.
