Allan Gardens, Botanical garden in downtown Toronto, Canada.

Allan Gardens is a public park and conservatory in Toronto's Garden District, with a 1,500-square-metre conservatory holding six greenhouses. The central Palm House is a glass and iron structure under a white dome, with a tall brick chimney beside it. A lower white building with an arched entrance stands to its left, and a white wing with a glass roof and a smaller brick section extends to the right.

The first site appeared after the land donation in 1858, but a fire destroyed the Victorian conservatory in 1902. Reconstruction followed in 1910 with a new design that shaped the current structure.

The name honors George Allan, a Toronto politician who donated the land for public use. The greenhouses now serve as a free retreat for local residents and provide a contrast to the surrounding downtown area.

The greenhouses open daily from 10 AM to 5 PM with free admission. The surrounding park offers an off-leash area for dogs and walking paths.

The Palm House maintains different temperature zones for various plant species and allows tropical types to grow in a northern climate. The greenhouses attract year-round visitors even during Toronto's long winters.
