Sultan Ahmed Mosque, Istanbul

Nicknamed for the blue tiles that adorn its interior, Sultan Ahmed Mosque represents an imposing figure in the city's history and skyline. Located in the historic Sultanahmet district and built in the early 17th century, this impressive religious structure has a total of six minarets, one main dome, and eight secondary domes. Originally commissioned to reassert Ottoman power in Istanbul and across the region, this mosque still functions as a site of worship today. However, the site welcomes visitors of all faiths to view its spectacular design, which mixes traditional Islamic architecture with Byzantine elements. Keep in mind you'll need to remove your shoes and women should cover their head and shoulders.
