It is a governmental placr now. But in Nowrouz people can visit. Not too much to see. Also the entrance that is shown by google is wrong.

Regardless of its ziggurat form, the floor has the most complete layout and space, and the front porch has been built in front of the floor, creating a beautiful arch with several arches. Registration has been registered as one of Iran's national monuments.

The Citadel was built during Qajar raj and today it is governorship of Birjand. Ziggurat architectural form of this building is very unique.

No public access. No photography allowed.

(Translated by Google) A magnificent building from the Qajar era, which is currently the governorate of South Khorasan, is located in the area of ​​this citadel. (Original) عمارتی باشکوه از دوران قاجار که در حال حاضر استانداری خراسان جنوبی در محوطه این ارگ قرارگرفته است.این بنا در پایه بصورت شش ضلعی ساخته شده است که در راس عمارت به شکل مخروط تبدیل شده است.

(Translated by Google) One of the most ridiculous things I saw is that this space is located in an administrative-administrative complex. There is also a governor's office here and this building is located in the governor's yard. While I think the governorship should be transferred to another place. (Original) از مسخره ترین چیزایی که دیدم اینه که این فضا در یک مجموعه اداری-انتظامی قرار داره. اینجا فرمانداری هم هست و این ساختمان در حیاط فرمانداری قرار داره. در حالی که به نظرم می بایست فرمانداری به جای دیگه ای منتقل بشه.

They don't let you to visit or take pictures there.

It's a historical castle but it's toobad that people aren't allowed to enter the bulding!

great view from outside but not so much to see inside.

Elegant

Its almost good.
