Welcome

Welcome to Castletown Girls' School's website! C.G.S. is an all-girls school situated on the Castletown Road, with a history spanning over three centuries. We also have a long and proud association with the Sisters of Mercy.
 
Currently, our school has approximately 190 pupils, 16 teachers, our caretaker Diarmuid, our special needs assistants Pauline, Rose and Gráinne and secretary Siobhán. This keeps our principal Ms. Murphy very busy as you can imagine! We also have a great Parents and Friends Association which you can read more about on the Parents' Page.
 
Overall, C.G.S. is a brilliant place to learn, work and have fun. Enjoy browsing our website and thank you for visiting!!
