The outdoor pool originally opened its doors back in 1935 by Portsmouth City Council but its condition significantly deteriorated over the years, making it unsafe to use.
Following multiple consultations, a multi-million pound project was launched last year to completely restore the pool to its former glory. The pool, which will open in the summer, will feature new changing rooms, new benches and tables, artwork, a fountain and, most importantly, a fully functioning outdoor swimming pool.
The council update said: “In the plant room, the designs for the shuttering are being finalised, and soon the walls will be ready for the concrete pour.
“Once the room is stable, the steel bars across the top will be removed. The ground around the edge of the pool is ready for surfacing, as soon a large tent will be erected over the pool to protect it from the elements while they move on to the next stage. The floor needs to be completely solid to support the structure.”

The filtration tank is pumping water out of the ground and back into the drain, so the heavy equipment doesn’t sink. | PCC
