The Sultan Uvays-Baba complex (XVII–XIX centuries) is one of the most revered places in the lower reaches of the Amu Darya. Its name is associated with the name uwais al-qarani. According to legend, he was one of the followers of the Prophet and lived in the village of Karain in Yemen.
Scientists believe that the construction was built by Sultan Muhammad Khorezmshah, but was destroyed during the Mongol invasion. In the early nineteenth century the Khan of Khiva Altuser builds a new building. The last construction of the mausoleum is attributed to Khiva Khan Allakuli (XIX century).
Today, the construction is a complex with a fairly developed infrastructure: a mosque serving the complex, "Holy pond", shopping centers, food outlets, a hotel, etc.
