History

St Joseph’s is an all‑girls secondary school founded by the Sisters of Mercy. It is the oldest secondary school in Castlebar, with origins dating back to 1853. The school stands on the historic grounds of the former Lord Lucan estate. In January 1845, the parish priest Fr Gibbons convened a public meeting in the local parish church with the aim of bringing the Sisters of Mercy to the town, leading to the establishment of the school.
