Swimmers taking to Salthill over the coming weeks will have to make do without Blackrock Diving Tower, which will be closed to the public.
Divers take to the tower in their droves year-round, but the structure is especially popular in good weather in spring and summer.
The diving tower will be closed temporarily during essential maintenance works from 2 May.
Galway City Council says the works are expected to last for two weeks — weather and tide dependent.
