P&O Cruises’ flagship Britannia will be fitted with new interiors, spa pods and a permanent art gallery as part of a multimillion-pound refit.

The 3,647-passenger ship, which launched five years ago in Southampton, entered the Damen shipyard in Brest, France, this week.

The line said the ship will come back into service on October 23 for a two-night cruise to Bruges before a transatlantic crossing to the Caribbean.

Britannia’s atrium (pictured), where live music and entertainment is available, will have a new colour scheme and design, according to the line.

Two “express spa” pods will be built into the Oasis Spa and Salon where massages and skin treatments will be available to passengers.

Passengers will also be able to enjoy two other new experiences – an Arctic cold room and an aroma steam room.

A permanent art gallery, next to Blue Bar on deck five, will be fitted on the ship.

The move comes after several temporary art exhibitions on Britannia.
