Gateway of India Built in Indo-Saracenic style, the foundation stone for the Gateway of India was laid on 31 March 1911. The structure is an arch made of basalt, 26 metres (85 feet) high. The final design of George Wittet was sanctioned in 1914 and the construction of the monument was completed in 1924. The Gateway was later used as a symbolic ceremonial entrance to India for Viceroys and the new Governors of Bombay.[3] It served to allow entry and access to India.[4]
