East Sussex Fire and Rescue Service were called to the former convent at around 5pm on Thursday, July 9 and have told those living nearby to keep their windows and doors closed.
Firefighters are on the scene of a massive blaze at a disused convent in East Sussex.
East Sussex Fire and Rescue Service (ESFRS) were called to the College Of The Holy Child Jesus on Magdalen Road in St Leonards at about 5pm on Thursday, July 9.
By 5.30pm, six fire engines were deployed to the site, as plumes of smoke were seen rising into the sky.
A water carrier and officers were also deployed.
No injuries have been reported.
Those living nearby have been advised to keep their doors and windows shut, ESFRS said.
Roads in the area are also being closed.
It is being reported that police and an electricity operator are also in attendance.
The fire is believed to have broken out on the third floor of the former Catholic college, which is understood to have previously been used as living accommodation at a school/college.
The Catholic college closed in 1976 and was later used as a language school before falling into disrepair.
The chapel remains Grade II listed.
As of 9pm the incident had been scaled down to three fire engines.
“Firefighting continues and steady progress is being made,” ESFRS said.
