Akbar's period was indeed rich in architecture. It represents the fusion of Indo-Islamic architectural techniques. He used indigenous techniques and techniques from other countries. His building projects can be divided into two phases:
1) First Phase: Many forts and palaces in Agra, Allahabad and Lahore were created. Agra Fort was supposed to be a fortress-palace and many monuments were built inside in various regional styles including Bengali and Gujarati styles. The same is visible in other palaces and fortresses in Lahore and Allahabad.
2) Second Phase: It revolved around the creation of his new capital at Fatehpur Sikri. A ceremonial capital was created as Sikri (near Agra), which was later named Fatehpur Sikri. All the buildings were made of red sandstone. The place had several beautiful monuments like Buland Darwaza, Panch Mahal, Jodha Bai's Palace and Salim Chisti's tomb.
