The tradition and style of garden design represented by Persian gardens or Iranian gardens (Persian: باغ ایرانی) is a style of "landscape" garden which emerged in the Achaemenid Empire. The paradise garden, an example of Persian garden, has influenced the design of gardens from Andalusia to India and beyond.[1][2] The gardens of the Alhambra show the influence of Persian garden philosophy and style in a Moorish palace scale, from the era of al-Andalus in Spain. Humayun's Tomb and the Taj Mahal have some of the largest Persian gardens in the world, from the era of the Mughal Empire in India.
