Sacred Relics (Topkapı Palace)
The various relics of Muhammad, his followers, and other items purportedly associated with Muhammad were brought to Topkapı Palace in Istanbul, where they remain to this day.
Tulip period
The Tulip period saw a flowering of arts, culture and architecture. Generally the style of architecture and decoration became more elaborate, being influenced by the Baroque period in movement. A classic example is the Fountain of Ahmed III in front of Topkapi Palace in Istanbul. The architectural style is a fusion of classical Islamic elements with baroque European ones, making it into distinct Ottoman architecture of the 18th century.
