Emergency services were called to the popular tourist attraction shortly before midnight on Sunday after fire took hold in a property near the Camden Stables.
Onlookers described the fire ‘moving very fast’, raising fears of explosions if it reached nearby restaurants.
The London Fire Brigade (LFB) said it sent 10 fire engines, including an aerial appliance, to the incident, while witnesses described seeing ‘lots of ambulances’ racing to the scene.
Crews from across central and north London fought to contain the blaze, which was ‘highly visible across the area’, for around three hours.
It is the second time in recent years that the north London market has been hit by a serious blaze.
