An early nineteenth-century house forming part of a unified terrace laid out in the 1780s, principally developed by a Mr Osburne and David Courtney. Although much of the original detailing of No. 60 was replaced during the renovation works of the 1990s, the overall character has been retained and it represents an important component of the streetscape. It displays a fine doorcase and fanlight, and intact setting details. The street was built to link the newly constructed Grand Canal to the upper class residential developments radiating from Leinster House. Built in pairs and rows over a period of thirty years, the fifty-four houses on the street were completed by 1834. The terrace is characterized by well-balanced proportions typical of the period, but the group at Nos. 58-62 boast more elaborate doorcases and greater window to wall ratios. Such variations within the groups in the street are a telling feature of its piecemeal development. Mount Street Upper is terminated by St. Stephen's Church at its east end, an impressive landmark focus making one of the key vistas of Georgian Dublin.
