The Jubilee Pool was designed in the early 1930s by Captain F Latham, the Borough Engineer. The pool was opened with great celebration in May 1935, the year of King George V’s Silver Jubilee.
The sea water pool was built on the Battery Rocks which were used as a natural bathing spot. It is a triangular shape with fluid curves giving it an Art Deco look.
In 2018 a project was set up to help geothermally heat a section of the pool through Crowdfunding and a mix of charity funding so that the pool could be open throughout the year rather than just the summer months. The Geo pool is heated to between 30-35 degrees by a local geothermal well and was opened to the public on 1st September 2020.
The Penzance pool is the first geothermal lido but not the first geothermal bath in the UK – the Romans beat us to it by 2000 years in Bath!
There is a café on site and changing rooms, but no lockers. Sessions in the geothermal pools have to be pre-booked. If you are visiting Penzance and fancy a dip in the lido then click here to find out more information about times and tickets.

I like the idea of geothermal heating – the only way I can imagine swimming outdoors in winter!
Or even in summer!
Oh yes – a good idea in the UK!
This is awesome!!! Thank you for sharing! This is going on the list! 💚
What a great asset – I would love to swim in a pool like this!
