Devonian Gardens is a large indoor park and botanical garden located in the downtown core of Calgary, Alberta, Canada. The park recently re-opened after a major $37-million renovation. Located on the Stephen Avenue pedestrian mall (8 Avenue SW) between 2 Street SW and 3 Street SW, the park is completely enclosed with glass and covers 2.5 acres (10,000 m2) (one full city block) on the top floor of The Core Shopping Centre (formerly TD Square). It is maintained by The City of Calgary Parks. The gardens include a living wall, koi ponds, fountains, a children's play area, and over 550 trees, as well as meeting/function space for special events. A full service restaurant is also planned.
