The work of the museum or gallery warder is to ensure the
safety of the objects
on display. Stationed at a suitable vantage point within the
gallery, the warder keeps
a gentle lookout for possible trouble from visitors (a swinging
bag, a camera poised, someone’s urge to touch), behaviour
that is against the rules or might endanger the exhibits.
Shifts are often very long, and warders must remain vigilant
Most warders are extremely well-informed about the paintings
and sculptures around them, and many turn out to be knowledgeable
enthusiasts in related fields.
