It is located 67 km east of Kulsary, Zhylyoi district, Atyrau region. The underground mosque was built by Kulshan Ata (XVIII-XIX centuries), known for his niece and disciple Beket Myrzaguly.A. Alekseev, a Russian topographer who visited the mosque in the 1950s, wrote about the first construction of the mosque: "... the mosque, built with a chalky roof, consists of two parts, which are 7 inches apart." In the first part, religious rites were performed, and in the second part, the body of the deceased was wrapped in a shroud. Legend has it that the owner of the mosque, a saint named Kulshan, lived in a room of the mosque when he was old enough, and was later buried there. His body was found in the underground mosque in 1851-1852 by the above-mentioned Russian topographer.In recent years, a two-room mosque has been built to preserve the mosque. The first is the entrance room, the second is domed with shells, through which you can enter the first two rooms of the underground mosque. The head of a separate four-sided stone in front of the mosque is cut out in a triangle and the inscription "Kulshan Ata" is written on it. A dark house has been built nearby for a long time, it has a lighthouse and the house is well equipped.Saint Kulshan lived around the end of the ХVІІІ century and the beginning of the ХІХ century. According to one source, the saint graduated from religious schools in Bukhara and Khiva. There are three different accounts of his relationship to Beket Ata: Alekseev's writings state that Kulshan was a disciple of Beket Ata, another version says that Aulie Ata was one of Beket Ata's 92 disciples, "Beket's son-in-law", and the third describes him as "Beket's nephew". There is a saying of Beket: "Anyone who comes to me from the west will first spend the night with the saint Kulshan". There was a snake in the saint's bed, and on Thursdays and Fridays there were fires.Kulshan also taught children like Beket, who went down in history as one of the first Arabic literate people in the Kazakh steppes.
