The Taj Mahal is considered the finest example of Mughal architecture, a style that combines lements from Persian, Indian, and Islamic architectural styles. In 1983, the Taj Mahal became a UNESCO World Heritage Site and was cited as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage." The Taj! An awe-inspiring poetry in marble stands high and serene by the banks of the River Yamuna is an inspiring result of the application of architectural and scientific research. The tomb laid out in rectangular shape can be approached through an immense gateway with huge arch and alcoves strewn on either side that stands tall and erect, as though guarding something precious. Three other smaller gateways follow the red sandstone towers topped with domes in white marble together make a pretty picture. The Taj is an experience of its own kind, while on the one hand its magnanimity is so sublime, so on the other the exquisite inlay work and detailed craftsmanship together with the calligraphy is simply amazing. The combination simply leaves one absolutely mesmerized. The sheer splendour of the mausoleum is consummate, and the vastness is simply monumental. The tomb is at the northern end with an expanse of greenery and fountains between it and the gateways. The ceiling is adorned with floral patterns and the décor of floors with geometric designs. The inner of the main structure is in lakhauri [a kind of earthen brick], which have been carefully covered with marble, whereas the adjoining structures are covered with red sandstone. Majestic and sensuous, glistening brightly in the afternoon sun, the bulbous dome and minarets with a slight inward tilt, have all been inscribed meticulously with the Holy Verses bringingforth the arabesque ornamentation. The white marble from Makrana in Rajasthan has added its own natural beauty to this mausoleum that attracts tourists from all over the world.
