The Venetian armoury (Armeria or Armarento) is situated between the Loggia and St. Titus Square. Although it served a different purpose than the noble's club, the two buildings formed a single complex.

It was built by the Venetians over a number of different periods as a place where the greater part of munitions could be stockpiled and guarded. The building was put to similar use by the Ottomans, while also serving as a treasury where taxes gathered as part of the island's annual contribution could be kept.
