Sultan Ahmed Mosque

The Sultan Ahmed Mosque (Turkish: Sultanahmet Camii) is the national mosque of Turkey, and is a historical mosque in Istanbul, the largest city in Turkey and the capital of the Ottoman Empire (from 1453 to 1923). The mosque is one of several mosques known as the Blue Mosque for the blue tiles adorning the walls of its interior.

It was built between 1609 and 1616, during the rule of Ahmed I. Like many other mosques, it also comprises a tomb of the founder, a madrasah and a hospice. The Sultan Ahmed Mosque has become one of the most popular tourist attractions in Istanbul.

Construction of the mosque started in August 1609 when the sultan himself came to break the first sod. It was his intention that this would become the first mosque of his empire. He appointed his royal architect Sedefhar Mehmet Ağa, a pupil and senior assistant of the famous architect Sinan as the architect in charge of the construction. The organization of the work was described in meticulous detail in eight volumes, now in the library of the Topkapı Palace. The opening ceremonies were held in 1617 (although the gate of the mosque records 1616) and the sultan was able to pray in the royal box (hünkâr mahfil). The building was not yet finished in this last year of his reign, as the last accounts were signed by his successor Mustafa I. Known as the Blue Mosque, Sultan Ahmet Mosque is one of the most impressive monuments in the world. It is one of the elements included in the complex built by Ahmed I to compete with Ayasofya.^[3]
