For the second time in nine months a former Hampshire acquatic centre is in flames.
Firefighters from at east seven stations across central Hampshire and Wiltshire have raced to World of Water on Greatbridge Road, just north of Romsey.
As crews fight the flames, the cause of the blaze is unclear but arson will be suspected.
The fire service warned nearby residents to stay inside and cloe windows to minimise the risk from smoke.
The fire service said: "Crews are tackling a blaze at the old World of Water site on Greatbridge Road in Romsey.
"Multiple fire engines are in attendance from Romsey, Ringwood, Lyndhurst, St Mary's, Eastleigh, Hightown, Fareham, along with crews from Dorset & Wiltshire fire service.
"Six firefighters in breathing apparatus are using jets to extinguish the fire.
"Local residents are advised to remain indoors and keep windows and doors closed due to smoke in the area."
