Abstract
Ximengding is one of the most eminent amusement quarters in Taipei, which was formed in the process of the modernization. Before the modernization, Taipei was constituted by three settlements, Dadaocheng, Mengjia and Castle; and these districts were clearly divided. During the periods of Japanese governance, the modern urban planning was carried out and merged three settlements into Taipei city. By the renovation, Ximending, a new commercial center, was produced as a by-product of the planning. This paper is set out to investigate how the spontaneous settlements were united and why Ximending could be a commercial district, by means of Space Syntax. As the result, we found the reason to make the conventional settlements isolated was not a requirement on the efficiency but cultural and ritual matters. And, the release from the conventional matters leaded Ximending to a commercial quarter.
