Samarkand is the second-largest city in Uzbekistan and the capital of Samarqand Province. It is most noted for its central position on the Silk Road between China and the West, and for being an Islamic centre for scholarly study. In the 14th century, it became the capital of the empire of Timur (Tamerlane) and is the site of his mausoleum (the Gur-e Amir). The Bibi-Khanym Mosque remains one of the city's most notable landmarks.
