Below is a photo gallery of the Nowruz celebrations in the year 2009 at the site of the tomb of Cyrus the Great at Pasargardae, the same area famed for being the location of the Persian Gardens of antiquity, and ancient engineering projects. The 2009 Nowruz celebrations at Pasargardae are available in YouTube for viewing.
What is remarkable is the prevalence of children and youth in the 2009 celebrations, lending credence to reports that there has been a markled increase in interest in Iran’s pre-Islamic heritage. The Nowruz is celebrated by a whole range of iranic peoples outside of Iran, including Kurds in iraq, Turkey and the Caucasus (the Nowruz is widely celebrated in the Republic of Azarbaijan), the Tats and Talysh of the Caucasus, as well as a variety of Turkic-speaking peoples in Central Asia.
