Fire crews are expected to be at the scene of a major fire at Sixfields Tavern until midnight tonight.
The fire broke out on Saturday afternoon and a spokesman for Northamptonshire Fire and Rescue Service said six pumps were in attendance trying to bring the blaze under control.
At 4.45pm a spokesperson for the fire service said fire crews were containing the blaze to stop it spreading further.
A large part of the roof of the building had collapsed but there were areas of the building that had not been damaged by fire and they were working to stop the fire spreading to that area.
It is understood that one person had been treated by ambulance crews for smoke inhalation as a result of the fire but there were no further details available.
The fire service said they will probably start to scale down the operation shortly to three pumps and two aerial appliances.
Fire crews will be at the scene until at least midnight. The spokesperson said it was too early to determine the cause of the blaze. The high winds this afternoon would have made the fire spread more quickly.
A Hungry Horse spokesperson told the Chron: “Unfortunately, there has been a major fire at the Sixfields Tavern.
“Thankfully, all of the pub’s customers and team members were swiftly evacuated and no-one was hurt. The pub will not be open for the foreseeable future and we will be working with the emergency services to establish the cause.”
A reader’s picture sent to the Chron’s Facebook page appears to show that the fire started in an area outside the building before spreading to the pub itself.
Police officers were directing Northampton Town fans away from Sixfields Stadium after their win over Northwich in the FA Cup.
The pub was recently refurbished in October and re-opened on October 16. According to the pub’s Facebook page, it was fully booked for Christmas Day with only limited availability for Christmas parties.
Fans at Sixfields Stadium have been tweeting pictures of the fire, which broke out just before kick-off on Saturday afternoon.
Northamptonshire Police are advising people to avoid the area.
In tweet, a spokesman said: “Fire at Sixfields Tavern, Sixfields, Northampton - roads are very busy & a number of closures are in place - people are advised to avoid the area.”
At 5.30pm, the spokesman added: “Firefighters are still tackling the fire at Sixfields - roads are likely to remain closed for some time - please continue to avoid the area.”
Fans watching the Northampton Town home game at Sixfields were told not to return to the North car park after the game.
Northamptonshire Police, Northamptonshire Fire and Rescue and East Midlands Ambulance Service are at the scene.
Bella Italia, which is next door to the pub, closed on Saturday night. The restaurant tweeted: “BellaItalia is closed tonight due to the fire next door. Sending our thoughts and good wishes to our neighbours.”
A spokeswoman for Bella Italia said staff were safely evacuated one police had alerted them to the fire at the nearby building.
“We are definitely not open this evening and we are not allowed back on site until tomorrow morning,” she said.
Staff would return to the scene on Sunday morning to assess the situation. The fire did not spread to the building but due to the high winds there may be the possibility that of smoke damage.
“We telephoned all of our customers who had bookings for this evening. There were two big parties booked which is understandable at this time of year.
“Everyone was fantastic and they were all very understanding. We don’t want to let people down but it is unavoidable.”
