Arts minister Alan Howarth has listed Plymouth Hoe's Tinside Lido Grade II after a campaign by the aj, and the 20th Century Society, to save the coastal Art Deco pool from destruction, saying that the 18m-diameter semi- circular pool is a rare and splendid example of a 1930s lido. Jill Sack, administrator of the 20th Century Society, said: 'This is great but slightly surprising news. So many lidos have been destroyed. We have been campaigning very actively for so long. We hope this one will now be restored.'
