聳立於薄扶林一山頭上的大學堂是一座糅合了都鐸、哥德及新文藝復興時期建築風格的華麗古堡式建築。
大學堂約於1861年由蘇格蘭商人杜格拉斯‧林柏建成，作為其公司總部及寓所之用，建築物亦因此命名為「杜格拉斯堡」。法國外方傳道會其後於1894年購入杜格拉斯堡，易名為「納匝肋修院」。1954年，香港大學購入納匝肋修院，並計劃改作學生宿舍。大樓自1956年起用作男生宿舍，名為「大學堂宿舍」。
納匝肋修院的主要建築特色仍得以保存。大樓一樓和二樓的柱廊飾有石柱，並建有具都鐸建築風格的尖拱，大門前有一對David’s Deer「四不像」雕塑。屋頂上的雉堞式女兒牆和小尖塔及角樓，是這座城堡式建築物最矚目的建築特色。
大學堂外部於1995年列為古蹟。
Situated on top of a hill in Pokfulam, University Hall is a charming castle-like edifice that blends Tudor, Gothic and Renaissance Revival architectural styles.
It was built around 1861 by a Scottish businessman, Douglas Lapraik, as his headquarters and residence and named after him as ‘Douglas Castle’. The French Society of Foreign Missions bought the building in 1894 and renamed it ‘Nazareth’. In 1954, The University of Hong Kong acquired it for use as a hostel for undergraduates. Now known as University Hall, the building has served as a hall of residence for men since 1956.
The significant architectural features that characterised Nazareth remain: colonnaded verandahs with Tudor arches delineate the first and second floors of the building, with a pair of David’s Deer guarding the entrance; while the embattled parapets and pinnacles on the roof as well as the corner towers are the most distinctive features of this castle-like building.
The exterior of University Hall was declared a monument in 1995.
