Around Mazutian and Hengxi stations, the vista begins to open. The window becomes a picture frame, enclosing distant mountains, fields on the urban fringe, and stepped stonework in the river, like a casually sketched natural landscape.
As the train continues, the view shifts from natural scenery to sites of human activity. The Sanying Line crosses the National Taipei University main campus, and fitting the metro into the existing landscape there became a design challenge.
The place where the line crosses the campus, Feiyuan Plaza, was designed by artist Chiang Chung-mou and features a monumental black-kite sculpture (of the bird of prey, not the toy) that echoes distant Yuanshan (“Mt. Kite”). To preserve the sightline and view, the route curves around the plaza. Also, the viaduct takes the form of an arched arcade, while a special paint finish simulates brickwork, recalling the architecture of Sanxia Old Street and helping the elevated structure blend into the campus and its surroundings.

The viaduct’s arched arcade and faux-brick paint finish evoke the architecture of Sanxia Old Street.
