Positioned at the opposite end of the yard to the gatehouse, the Clarence building closes the vista along the main thoroughfare. Begun in 1827 (the first structure to be built on the site), it was originally used as a liquid store with one floor each of spirits, vinegar and beer (use of iron for the roof, doors, windows etc. was to mitigate against the flammability of alcohol). As needs changed, so did the role of the Clarence Store, and latterly the building was used for the storage of spares and components.
