Kalazeyva Mausoleum (Azerbaijani: Kələzeyvə türbəsi) is a historical and architectural monument located in Kalazeyva village of Ismayilli District.
Due to the location of an ancient cemetery and shrine in the village of Kalazeyva, the inhabitants of the surrounding areas also used here for burial.
It is clear from the inscription on the wall on the left side of the entrance of the mausoleum that the monument was built in the first half of the 19th century on the graves of the family members of Mostafa Khan of Shirvan.
Here, the transition from the octagonal base to the inner dome was made by means of small squinches similar to the ornamental squinches of the second tier.
Other details of the tomb, the profiles of the ledge and tsokol, the frames of the arches and other details reflect the new shapes created as a result of relations with Russia.
