More than fifty prefabricated mobile homes burned down on Sunday evening when a fire broke out at the Pueblo Fiesta Lazy Days holiday park in Mollina.
Around 90 people were on the site at the time, most of them British, said municipal sources. No one was injured in the fire although the emergency services treated several people for shock and panic attacks.
Evacuated residents and holidaymakers were put up at the nearby Ceulaj youth residence, or taken in by friends or relatives.
Firefighters from the provincial fire consortium were deployed to the site, in the area known as Cañada Realenga, along with members of the Civil Protection organisation, health emergency services, Local Police and Guardia Civil officers.
The flames were brought under control at around 7pm, after more than two hours fighting the blaze on the ground and from the air.
The blaze did not spread outside the holiday park but destroyed most of the homes, leaving just a small group standing.
As well as British nationals on the site, many of whom live there all year round, or for long periods of time, official sources said there were also some Dutch citizens, among other nationalities.
The mayor of Mollina, Eugenio Sevillano, told SUR on Sunday evening that the local people rallied round to help the evacuated residents, providing food and other basic essentials for those staying at the Ceulaj centre which was empty at the time.
Others offered their tractors and farm machinery to help clear the ash and rubble.
The Pueblo Fiesta Lazy Days, known in the area as "the English campsite", was opened 12 years ago.
The cause of the fire is not yet known.
