The cause of a fire at the Holly Tree pub in Northdown Road is believed to be arson.
Kent Police officers are investigating the fire that happened between 8am and 9am on Sunday 16 April.
A Kent Police spokesman said: “The cause of the fire is believed to be suspicious and officers are continuing to enquire into the circumstances.”
Some 20 firefighters and six engines, including the specialist height vehicle, were used to tackle the blaze which was finally brought under control at 12.55pm.
