A Great Piece of Architecture: Blue Mosque In Istanbul, Turkey

The mosque was designed by architect Mehmet Aga in 1609, where the commissioner Sultan Ahmet I eagerly wanted the mosque finished that he also helped with the construction. The Blue Mosque originally included a madrasa, a hospital, a primary school, a market and the tomb of the founder. However, most of these buildings were torn down in the 19th Century. Inside of the mosque the walls are covered with mosaic tiles which extend from the ground to the roof.
