原名霍格別墅，1863年始建。因在約大校舍中排列第四，故稱四號樓。常常與之前方的大草坪被一起提及，是華政“帳篷精神”的象征。

四號樓原名霍格別墅，于清同治二年（1863年）始建，次年基本建成，1899年完成大修。霍格別墅基地面積754平方米，建筑面積1275平方米，兩層共25個房間，樓頂筑有塔樓，可供憑眺。建筑的主要構件為木料，木門、木窗、木柱、木梁、木地板、木樓梯、木壁爐架等。底層南側有一排3米進深的柱廊，頂部為黑鐵皮，可供轎車直接駛至門前。

The construction of Building No.4, originally known as “the Hogg’s House”, started in 1863 and was basically completed in one year. The building went through a major repair in 1899. The Hogg’s House covered an area of 754 square meters, with a construction area of about 1275 square meters. The two-storey building had 25 rooms in total. There is a tower on its roof, where people can look as far as they wish. The main components of the building include timber, wooden doors, wooden windows, wooden pillars, wooden beams, wooden floors, and wooden mantels, etc. On the southern side of the bottom floor is a 3-meter-long colonnade with black sheet on the top, through which one can drive cars straight to the front door.

四號樓常常與之前方的大草坪被一起提及，是因為根植于此的“帳篷精神”。1979年華政第二次復校，迎來了第一批310名學生，然而，除了復旦分校將東風樓歸還華政外，其他校舍仍然分別被幾家單位占用。以徐盼秋、曹漫之為首的一批黨政領導決定以學生為先，先建圖書館與教學大樓，黨政工團的辦公用房則是由租借的5頂帳篷組成，搭建在大草坪上。帳篷內冬冷夏炎、光線昏暗、空間狹小，可是大家辦學的熱情不減，學校黨委于此舉行院務會議、布置檢查工作、接待來信來訪人員等，一住就是數年。“帳篷精神”的故事是學校復校伊始艱苦創業的真實寫照，也體現著華政人凝心聚力，為法學教育事業不懈奮斗的精神。

As the fourth building on the campus of St John’s University, it is known as Building No.4, standing together with the grand lawn in front of it, because the “Tent Spirit” that originated here has inspired generations of students. In 1979, the second reopening of ECUPL welcomed the first batch of 310 students. However, except East Wind Building, which was returned to ECUPL by the branch of Fudan University, other buildings were still occupied by other work units. The Party and administration leadership headed by Xu Panqiu and Cao Manzhi decided a library and a teaching building should be built first, and 5 rented tents set up on the lawn as the offices of the Party and administration. The dark and small tent offices were of course not very comfortable: freezing cold in winter and scorching hot in summer, but those working inside were all passionate for restarting the university. For years, in the tents, the party committee of the university held meetings on campus affairs, arranged inspections, received letters and visitors, and so on.The “Tent Spirit” is an authentic narration of the arduous pioneering efforts of the university in the early years after its reopening. It also mirrors the spirit of ECUPLers, i.e., joining hearts and hands and making unremitting efforts for the cause of legal education.
