The capital of Iran, Tehran, is now home to almost 8 million residents. For the most part, it is a modern city with a modern skyline situated in front of the snow covered backdrop of the Alborz Mountains. Fortunately, parts of the beautiful old town are still intact. From the Sepahsalar (Shahid Motahari) mosque with its eight minarets, visitors have a good view of the city. The large Tehran bazaar, open daily except Fridays and religious holidays, is among the world's largest. There is another bazaar in Tajrish, a suburb north of the capital city. In the maze of roofed alleyways merchants sell valuable carpets, silver and copper items, foods and exotic spices. Arts and crafts can also be found at the bazaar. In Tehran there are also a number of significant museums, including the Abgineh Museum (Iranian pottery), the Rea Abbasi Museum (a collection of Iranian calligraphy and painting), the National Museum, the Carpet Museum and the Ethnological Museum. The National Library and the Zoo are also worth a visit. Side trips into the nearby Alborz Mountains are also possible from Tehran. Here visitors can ski from January until March at winter sports destinations with cable railways and ski areas. The historical cities of Rey, Varamin, Qazvin and Shemshak can also be easily reached from Tehran.
