The standard plan of Ottoman architecture was inspired in part by the example of Hagia Sophia in Constantinople/Istanbul, Ilkhanid works like Oljeitu Tomb and earlier Seljuk and Anatolian Beylik monumental buildings and their own original innovations. The most famous of Ottoman architects was (and remains) Mimar Sinan, who lived for approximately one hundred years and designed several hundreds of buildings, of which two of the most important are Süleymaniye Mosque in Istanbul and Selimiye Mosque in Edirne. Apprentices of Sinan later built the famous Blue Mosque in Istanbul.
