未央宫 / Weiyang Palace
未央宫 / Weiyang Palace enters the wiki through Hanji 171 part 2 as the palace 刘邦 orders built on the old Qin Zhangtai Palace base after the early 西汉 court has moved toward 长安. The episode says it is completed in Han year nine.
The source treats Weiyang Palace as the second half of the new capital’s court geography. 长乐宫 begins as Liu Bang’s residence, but Weiyang Palace later becomes the ordinary imperial residence while Changle Palace becomes associated with the empress dowager.
This makes Weiyang Palace a material sign that the Han founding order is moving from campaign settlement into durable court routine. The same episode that describes regional kingship suspicion also shows the center building the physical spaces from which that suspicion and administration will operate.
