The Ismailiyya Palace (Azerbaijani: İsmailiyyə Sarayı) is a historical building that currently serves as the Presidium of the Academy of Sciences of Azerbaijan. It is located on Istiglaliyyat Street in Baku. The palace was constructed for the Muslim Charity Society by Józef Plośko at the expense of the millionaire Musa Naghiyev in commemoration of his deceased son Ismayil, and was named Ismailiyya after him. Construction began in 1908 and ended in 1913.
The building of mosques is appointed to be in a place called "Gapan Dibi" in the center of the city. Although it was initially planned to build a garden with fountains surrounding the mosque, the Christian clerics, who had great influence in the period of the Russian Empire, prevented the construction of such a mosque near the Alexander Nevski Church, which is called the Golden Church (Qızıl kilsə).
