Mausoleum of the Imāmzādeh Yahya Bin Zaid
The shrine of the Imāmzādeh Yahya Bin Zaid Bin Imām Zin Al'abeddin (A) (107-125 Lunar Egira) is located in the city of Gonbad-e Kāvus (Golestān region). This building dating back to the Mongol period was renovated during the Safavid era, at the time of Nasreddin Shāh Qājār and in recent years it has been rebuilt again.
This Imāmzādeh consists of a large building and a large courtyard, a covered space, one Shabestan, from a public fountain, from a porch worked in mirrors and around there are many stopping places for pilgrims.
The only trace left of the original architecture is a mihrab worked in stucco belonging to the ilkhanide period on which two sides are inscribed verses of the Holy Quran.
This mausoleum that is next to the area of the ancient city of Jorjān, in the past was part of the 4 pilgrimage sites of the ethnic Turkmen Yomut group, in particular the Atābāi and the people of the Katul area who were called Gharan Kimān; Gharan Kimān or Gharan Kamān who was originally "Qārnaki Imām" with the meaning of Imam dressed in black.
Other places of pilgrimage to Varāmin, Sabzevār, Gorgān, Nishābur, Myāmi Mashad, Semnān and Hamedān are attributed to Yahya Bin Zaid and this is not correct; this error derives from the similarity of name.
