The McLennan Library Building stands on the site of Jesse Joseph's former mansion, named Dilcoosha, in the Golden Square Mile.
The mansion later served as a Canadian Officers' Training Corps headquarters during World War I and afterwards as the first home of the McCord Museum.
The library building was named in honour of Isabella McLennan, who had made a large donation to McGill in order to purchase books.
These collections are used to aid teaching, learning and research for McGill students and the general public from all fields of study.
Première Moisson, a chain of artisanal bakeries in Quebec, was located in the basement of McLennan Library until the end of the 2018/19 school year.
The new space is located on the 6th floor of the McLennan Library building and was designed with the user preferences in mind.
The centre of the tranquility zone showcases a Zen Garden which contains stress relieving activities for students to engage with in between periods of work.
