About our school

Lecale Trinity Grammar school was established in September 2024 and is an 11-19 co-educational, all ability voluntary grammar school in Downpatrick. 

The school is an amalgamation of two Lasallian schools, De La Salle High School and St Patrick’s Grammar School, and a school from the Mercy tradition, St Mary’s High School. Lecale Trinity Grammar School is a Lasallian Catholic school in the trusteeship of the De La Salle Congregation.   

The vision for the new school is that it should be located on the Lasallian Campus pending capital investment. In the interim, the school will operate over two sites: 

Mercy Campus: Year 8 and Year 9 

Lasallian Campus: Years 10-14
