St. Enda's School was an Irish language secondary established in 1908 by Irish nationalist Patrick Pearse. Originally Pearse's school was established in 1908 at Cullenswood House, Ranelagh before moving to the Hermitage in Rathfarnham in 1910. After Pearse was executed for his part in the 1916 rising, and due to increasing financial worries, the school closed in 1935. Today the site is occupied by the Pearse Museum.

Patrick Henry Pearse was an Irish teacher, barrister, poet, writer, nationalist, republican political activist and revolutionary who was one of the leaders of the Easter Rising in 1916. Following his execution along with fifteen others, Pearse came to be seen by many as the embodiment of the rebellion.
