Part of a religious group of structures with the adjacent convent and school,Saint Michael's, with its imposing tower, is an important social building in the town of Portarlington. Its finely executed stonework articulates its Gothic Revival form while decorative features such as its illuminating windows enliven an otherwise austere exterior.
