In those days,when the island was under the Ottoman rule, sponge fishing was thriving and the place was used for sponge storage. This can also be demonstrated by the copper hooks on the ceiling where the sponges were hung to dry.
During the Italian occupation in 1912, the same place was used by the Italian forces for food storage. In 1943 it survived the German bombardment of the island despite the fact that most bombs fell very close demolishing Saint Nicolas church and the surrounding buildings.
