一、名称考义
故宫又称紫禁城。中国古代讲究“天人合一”的规划理念，用天上的星辰与都城规划相对应，以突出政权的合法性和皇权的至高性。
天帝居住在紫微宫，而人间皇帝自诩为受命于天的“天子”，其居所应象征紫微宫以与天帝对应，《后汉书》载“天有紫微宫，是上帝之所居也。王者立宫，象而为之”。
紫微、紫垣、紫宫等便成了帝王宫殿的代称。由于封建皇宫在古代属于禁地，常人不能进入，故称为“紫禁”。但明朝初期称为“皇城”，直接称呼为“紫禁城”则大约始于明朝中晚期。
二、建筑规模
北京故宫由明朝皇帝朱棣始建，设计者为蒯祥（1397—1481年，字廷瑞，苏州人）。占地72万平方米（长961米，宽753米），建筑面积约15万平方米，占地面积72万平方米，用100万民工。
共建了14年，有房屋9999间半，实际据1973年专家现场测量故宫有大小院落90多座，房屋有980座，共计8707间（而此“间”并非现今房间之概念，此处“间”指四根房柱所形成的空间）。
