Our Lady and St Michael's Convent, Abergavenny is late 18th century. It was extended to the north in 1956 (dated). The house was probably reroofed at this time and given the dormers and new chimneys. The house became a Convent of Breton nuns in 1906 and they ran a girls school for many years.

The building is roughcast render, unpainted, having a tiled roof with red brick stacks. It has a double depth central entry plan, two storeys and attic, five windows, 2 : 1 : 2, with the central portion breaking forward with low crowning pediment. There is a small portico with fluted columns, steps up to porch and a panelled door. The windows are all 6 over 6 pane sashes with keystones. The pediment has a central coat-of-arms. There is a coped parapet and a moderate pitch roof with two gabled dormers with bargeboards. The north gable has a large teaching block dated 1956 attached.
