A modern capital, Tehran extends from the southern slopes of the Alborz Mountains to the Kevir desert. Its symbol is the Azadi Tower that forms an arch underneath. Its 148 ft high summit offers a great panorama of the city. The bazaar covers a large area of the historic neighbourhood that has become the town centre. Wandering around the stalls, shops and workshops in the heart of a maze of streets and alleys is a sheer delight. Remember that artisans are organised by profession. Nearby, the mosque of Imam Khomeyni is worth a visit for its lively. In the administrative neighbourhood, the Shahid Motahari mosque dating back to the 19th century is the epitome of Qajar architecture. Worth seeing is the external earthenware depicting characters and floral patterns. In the area of Shemiran, the former royal residence of the Pahlavi dynasty contains 18 palaces and residences on a park of over 247 acres. These date back to the 1930s. The White Palace built by Riza Chah is renowned for its carpets and French furniture. From the north of Tehran, you can reach the heights of the Alborz with the cable car that climbs up to Mount Toshal.
