The masterpiece, Suleymaniye Mosque, built in the mid 1500s, is located on Istanbul's highest hill in the heart of the historical peninsula of Istanbul. It was commissioned by the Suleiman, the Magnificent himself. (It is not the Blue Mosque as some people might think). For 462 years, the Suleymaniye Mosque was the largest mosque in the city only surpassed in 2019 by the Camlica Mosque.
It was built by the famous 'most prolific' architect in all of Ottoman history, Mimar Sinan. The mosque actually houses the tombs of the Sultan Suleiman and his famous wife, Hurrem Sultan (Roxelana)
