This building was designed by Allan Merrick Jeffers. It has been known as the Parliament Building, Legislative Building and (most commonly today) as the Alberta Legislature Building. It is, in fact, at least the fourth building to house the Alberta Legislature. The first was the Thistle Theatre & Ice Rink, the second was the McKay Avenue School and the third was the original Terrace Building.
