It was built during the Ottoman Empire, and it is located in the old part of the city, or more specifically in Vratnik, in Jekovac Street.
This building was built in 1809, and it is located within the ramparts of Vratnik. Name Yellow bastion came from the yellow colored stone, but anyone from Vratnik will call it by its other, better known name. So, when you hear someone from Vratnik says: “Let’s go to the Cannon”, you know that he is thinking on the Yellow Bastion.
