Mihrimah Sultan
After his death Mihrimah accomplished his work, as well as the Rüstem Pasha Mosque (1561–63), one of Mimar Sinan's most impressive projects. Rüstem supported Mihrimah's charitable foundations, for example, the Mihrimah Sultan İskele Camii (Mihrimah Sultan Mosque in Üsküdar, 1540–48; a known külliye in Istanbul, Mimar Sinan project). Rüstem was also Mihrimah's mentor, particularly concerning political and financial decisions. His last will from 1561, provides evidence of his confidence in his wife. Rüstem's brother Sinan Pasha (who died in December 1553, a turbulent year for the family), was later buried in Mihrimah Sultan Complex in Üsküdar. The daughter, Ayşe Sultan (born 1547), was married in 1561 to Şemsi Ahmet Pasha.
