No 4 [Lower Gallery] Deck, location GH-4: Looking to starboard from near the centreline at roughly frame 57. The open double doors on the left are for the Isolation Ward. The adjacent compartment just beyond the ventilation pump is the No 1 Examining Room, while the door at the end of the corridor leads to the open deck space outside. The sliding door on the centre right is for the Main Office.

This is part of a series of photographs taken during the final stages of HMS Ark Royal's last major refit which was completed in 1970. The location references are derived from the deck plans in the latest edition of the ship's NBCD book.
