The next place worthy of visiting is Masjid on-Nabi (the Prophet's Mosque, known as Masjid-e Shah or the Royal Mosque until the downfall of Pahlavi dynasty) located in the south of Imam Khomeini Street. Apart from being in the heart of bazaar, it is a 19th-century Qajar creation (during the reign of Fath Ali Shah) which will forcibly remind you of the mosques of Shiraz, particularly Masjid-e Vakil, because of its ceramic floral decorations and tile mosaics. The magnificent four ivans round a large central courtyard are richly decorated with colorful tiles and Kuffic inscriptions.
