Hydrographic charts or Admiralty charts are maps designed as aids to navigation at sea. They are produced by the British Admiralty. The Hydrographic Office, a sub-department of the British Admiralty, was established in 1795 and issued its first officially published Admiralty chart in November 1800. Admiralty charts show navigational hazards such as reefs and wrecks, and navigational aids such as lights, buoys and beacons. Nineteenth-century charts may show coastal elevations and topographic views, useful to identify landfalls and prominent fixing marks. They may also include details of coastal forts and other defenses. Admiralty charts are continually updated and corrected. These corrections were often made by amending the original engraved plate and issuing the chart as a new edition; in other cases the chart was completely re-drawn.

Genuinevintage chart with last correction (update) in 1927. This edition is genuinely almost 90 years old and not a recent copy or recent printing as, you will find, most charts are. As charts were updated (corrected) older versions would be discarded, and it is a wonder that these older editions have survived to this day.
