Mashhad is a city of pilgrimage and spirituality in Iran, where millions of faithful flock to pay their respects to Imam Reza, the eighth Shia Imam and a descendant of Prophet Mohammad. His shrine, the Haram-e Razavi, is a complex of mosques, courtyards, museums, and libraries that dazzles with its golden domes, minarets, and tilework. Mashhad also offers a glimpse into the rich history and culture of Khorasan, a region that once spanned from Central Asia to the Caspian Sea. You can explore the ancient city of Tus, the birthplace of the poet Ferdowsi, the tomb of the mystic poet Attar, and the Nader Shah Museum, dedicated to the founder of the Afsharid dynasty.
