**Trifora** is a type of three-light [window](/source/Window). The trifora usually appears in towers and belfries—on the top floors, where it is necessary to lighten the structure with wider openings.[1][2][3]

## Overview

The trifora has three openings divided by two small columns or [pilasters](/source/Pilaster), on which rest three arches, round or acute. Sometimes, the whole trifora is framed by a further large arch. The space among arches is usually decorated by a coat of arms or a circular opening. Less popular than the [mullioned window](/source/Mullioned_window), the trifora was, however, widely used in the [Romanesque](/source/Romanesque_architecture), [Gothic](/source/Gothic_architecture), and [Renaissance](/source/Renaissance_architecture) periods. Later, the window was mostly forgotten, coming back in vogue in the nineteenth century, in the period of [eclecticism](/source/Eclecticism_in_architecture) and the rediscovery of ancient styles ([Neo-Gothic](/source/Gothic_Revival_architecture), [Neo-Renaissance](/source/Renaissance_Revival_architecture), and so on). Compared to the mullioned window, the trifora was generally used for larger and more ornate openings.
