Suleymaniye Mosque captured by Kamil Firat

Most travellers to Istanbul pay a visit to the historic Sultan Ahmed Mosque, better known as The Blue Mosque. However, just 20 minutes away is another marvel, Suleymaniye Mosque, considered one of the largest mosques ever built during the Ottoman empire. The Byzantine architectural masterpiece has a massive central dome, pierced with 32 openings, which illuminate the mosque's interiors. It's the work of the celebrated Ottoman architect, Mimar Sinan (1490-1588).
