Valletta is surrounded by high bastions. Protecting the west end are two cavaliers, a term originally used to define a knight who once stood on these platforms to protect the city. This sentry box is part of the St. James Cavalier. This massive limestone wall was built in the mid-16th century within a couple years of when Valletta was founded. In 2000, part of this structure was transformed into the St. James Cavalier Centre for Creativity. They host a variety of cultural activities ranging from the visual arts, theater and music.
