What material is the base platform of the Taj Mahal made of?

The base platform of the Taj Mahal is made of red sandstone. The famous white-marble mausoleum rises above this contrasting sandstone foundation and terrace, creating one of the monument’s defining visual effects.

This choice reflects Mughal architectural traditions, in which red sandstone was widely used for major structures and white marble was reserved for especially important surfaces. The sandstone was quarried near Fatehpur Sikri, about 45 kilometres from Agra, while the marble came from Makrana in Rajasthan, roughly 400 kilometres away.

The answer is sometimes confused because visitors mainly notice the enormous marble terrace and the white tomb above it. The platform is also not a simple solid block: the builders created a substantial brick-and-mortar structure supported by foundations designed for the Yamuna riverbank. Red sandstone appears elsewhere throughout the complex, including the main gateway, enclosing walls, mosque and jawab, the building that balances the mosque. Together, the red sandstone and white marble give the Taj Mahal its carefully planned colour contrast and symmetrical Mughal character.
