The center of Zubiena is quite small and centers around a large square that is quite remarkable from an urban planning perspective. It features a large fountain, the town hall, and, opposite it, at the top of a flight of steps, the imposing façade of the parish church of San Nicolao, dating from 1756. Its exposed brickwork lends a warm and captivating tone. Although relatively rare in the Biella area, where this is the largest example, brick Baroque church façades are common in other parts of Piedmont and, overall, constitute a distinctive feature. Zubiena's Baroque style, however, is simple and unadorned, with two clear-cut string courses that restrain the upward thrust of the six pilasters. Next to it stands the very tall 19th-century bell tower: anyone observing the Serra from the Biella plain, even from afar, will easily recognize it.
