The spectacular main lobby is home to several gorgeous Corinthian columns holding up the central dome, which reaches 30 meters in height. The impressive structure is the central aesthetic focus of the building. The dome's accompanying stained glass is breathtaking in color and spectacle, and the entire structure is a rare example of Taiwanese architecture of the time.
雄偉的大廳，是由多根華麗的羅馬科林式石柱撐起，中央圓頂塔高近 30 公尺，氣勢磅礡，是整幢建築的視覺焦點，圓頂下的彩繪玻璃，瑰麗色澤，讓參觀民眾驚嘆不已，整座博物館也一直被視為台灣近代難得一見的建築瑰寶。
