It's the 50th anniversary of the Portishead Open Air Lido today and a range of events are being planned to celebrate.
There will be fairground rides, zorb walking and a balloon race.
Volunteers at the lido will also be recreating the moment when the pool was officially opened by Alderman Smith. To mark the opening Mr Smith poured a kettle of hot water into the pool. Today a similar kettle pouring ceremony will be conducted by North Somerset MP Liam Fox.
