The Guernsey Fire and Rescue Service, Guernsey Police, and Guernsey Civil Protection Volunteers all remain on the scene with flames visible at 07:30.
There have been no reports of any injuries at the time of writing.
Photographs shared to social media by people in the area earlier this morning show tall columns of bright orange flames with billowing smoke.
The fire and rescue service has described it as a “structure fire”.
All roads around La Vallette – including down to the Bathing Pools, the Val des Terres, and Havelet are closed.
A spokesperson for Bailiwick Law Enforcement asked everyone to “please find alternative routes”.
A subsequent message said: “Due to the amount of smoke that is coming from the incident at Octopus, we would recommend that all residents in the nearby area keep all doors and windows closed for their own comfort and safety.”
