Each and every discussion revolving around the history of windmills in Malta has always and, wrongly so, focused on their exclusive use for grinding wheat and barley, without taking into consideration that some of these windmills, in particular those situated behind the fortified walls (but not only), could have had a dual function; that of being powder mills and machines for the grinding of corn. Old maps of the Grand Harbour have clearly documented the use of windmills in Malta forthe exclusive production of gunpowder at the turn of the seventeenth century. For security reasons, gunpowder mills were mostly situated within the city walls. However, in the absence of historical records, the major difficulties are: which of these windmills were used for milling grain? Which had a dual function? Which were used exclusively for producing gun powder? This paper seeks to answer these questions.peer-reviewe
