It surely is @silversaver888 😊
That pillar so looks out of place in that wall. The whole structures and fortifications has been updated and added too over the time between the 11th and 14th century. It could well be there was something else and that pillar is the only remaining part of that building.
Thank you so much, happy to share my adventures and views 😊I loved living in that city. There was so much to see, and even after a year. I still haven’t seen it all.

Awww and you are so kind 🤗🥰
Have a wonderful Sunday 👋🏻😉
