One of the tourist attractions of Qeshm Island is the Castle of the Portuguese which was built in 1507 on the northern side of Qeshm Island by a Portuguese sailor called Afonso de Albuquerque. By constructing several castles in Iran’s southern ports and islands, the Portuguese acquired full authority over southern Iran, and thus gained control over the marine commercial road between India and Europe, and their dominance on this important marine waterway lasted 110 years.
