@osmanli_tarihi_61: Rumeli Hisarı, built by Sultan Mehmed II in 1452, stands proudly on the European side of the Bosphorus in Istanbul. It was constructed in just four months to control naval traffic before the conquest of Constantinople. With its massive towers and strategic position, the fortress played a key role in cutting off aid to the Byzantines. Today, it remains a symbol of Ottoman strength and determination, overlooking the Bosphorus like a silent guardian of history. #History #ottomanempire #historical #mehmet #fatihsultanmehmet
