Gateway of India [SEP] Design and architecture
The gateway's arch has a height of with its central dome being in diameter. The monument is built of yellow basalt and reinforced concrete. The stones were sourced locally while the perforated screens were brought in from Gwalior. The monument faces towards the Mumbai Harbour. There are four turrets on the structure of the gateway, and there are steps constructed behind the arch of the gateway which lead to the Arabian Sea. The monument features intricate stone latticework (also known as the "jali" work). The Scottish architect, George Wittet combined elements of the Roman triumphal arch and 16th-century architecture of Gujarat.
