Hidden among the bustling streets of the Eminönü district, the Rüstem Pasha Mosque is a dazzling yet often-overlooked gem of Ottoman architecture. Built in the 1560s by the famed architect Mimar Sinan for Rüstem Pasha, the grand vizier of Suleiman the Magnificent, the mosque is celebrated for its exquisite İznik tiles. Every inch of its interior is adorned with intricate floral and geometric patterns, making it one of the most beautifully decorated mosques in Istanbul. Though smaller than other imperial mosques, its artistic brilliance offers an unforgettable experience for visitors seeking a quieter yet visually stunning place of worship.
