Allan Gardens Conservatory 

Allan Gardens was founded in 1858 by local politician George Allan who offered the Toronto Horticultural Society a 5 acre plot of land to develop a garden, the cast-iron glass domed Palm House was built in 1910, making it one of the oldest parks in Toronto. The conservatory is open 365 days a year with free entry and I found it to be the perfect tranquil escape from the busy city.
