The park also featured two air raid shelters, one each on the Ann and Wickham Street frontages. Similar shelters [602473] were constructed at many inner city sites in the early 1940s as part of Queensland’s wartime defences. In 1961, the Council prepared plans to convert the Wickham Street air raid shelter into a toilet block. These were evidently demolished by the time the Council planned the construction of a new toilet block in 1973. This entailed the demolition of the remaining air raid shelter on Ann Street. (CHIMS)
