Portuguese castle
The works of the Portuguese fortresses in Qeshm and other forts in the eastern part of the valley, known as the Naderi fortresses, which were equipped with large balls of that time, are seen in Qeshm. The fortress has been tasked with supporting the castle of Hormuz, which included providing fresh water for the Portuguese castle in Hormuz. The construction of this castle in 1621 led King Abbas to fight against the Portuguese and expel them from the Gulf coast.
