The sports building at Queen’s Park Annexe in Chesterfield has gone up in flames.
Firefighters from Chesterfield, Staveley and Clay Cross were called to the site on Boythorpe Road at about 10.55pm last night.
A spokesman for Derbyshire fire service said: “The incident involved a blaze in the sports building which was well alight.
“Firefighters used three main lines to put out the fire.”
Crews left the scene at about 2am and will return later this morning to assess the damage.
Prior to this incident, at 10.35pm, firefighters from Chesterfield and Staveley battled a blaze at the old magistrates’ court building on West Bars.
It is understood a wheelie bin had been set alight and pushed up against the building, causing the flames to spread.
Police were in attendance at both incidents.
