• Akbar was the first Mughal ruler who had the time and means to undertake construction on a large scale. He built a series of forts, the most famous of which is the fort at Agra. Built in red sandstone, this massive fort had many magnificent gates. For their forts, the Mughals drew on the developed Indian tradition of fort-building, such as the ones at Gwaliar, Jodhpur, etc. The climax of fort-building was reached at Delhi, where Shah Jahan built his famous Red Fort.
• Akbar took a close personal interest in the work of construction, both at Agra and Fatehpur Sikri. Persian or Central Asian influence can be seen in the glazed blue tiles used for decoration in the walls or for tiling the roofs. But the most magnificent building was the mosque and the gateway to it called the Buland Darwaza (the lofty gate) built to commemorate Akbar’s victory in Gujarat. The gate is in the style of what is called a half-dome portal. What was done was to slice a dome into half. The sliced portion provided the massive outward facade of the gate, while smaller doors could be made in the rear wall where the dome and the floor meet. This devise, borrowed from Iran, became a feature in Mughal buildings later.
• With the consolidation of the empire, the Mughal architecture reached its climax. Towards the end of Jahangir’s reign began the practice of putting up buildings entirely of marble and decorating the walls with floral designs made of semi-precious stones. This method of decoration, called pietra dura, became even more popular under Shah Jahan, who used it on a large scale in the Taj Mahal, justly regarded as a jewel of the builder’s art.
