صقللي محمد باشا
In this late stage of his life, Sinan tried to create unified and sublimely elegant interiors. To achieve this, he eliminated all the unnecessary subsidiary spaces beyond the supporting piers of the central dome. This can be seen in the Sokollu Mehmed Pasha Mosque in Kadırga, Istanbul (1571–1572) and in the Selimiye mosque in Edirne. In other buildings of his final period, Sinan experimented with spatial and mural treatments that were new in the classical Ottoman architecture.
