[1] In the year 1849 Bishop Antony who came from Rome[4] invited the Congregation of Christian brothers from France to found a primary school at Mangalore to provide education to the children of the vicinity.

The School played a very significant role in the destiny of thousands of Mangaloreans of all religious and castes.

From the year 1968 the Management of the School was taken over by the Catholic Board of Education, based at Bishops House Mangalore.

The 1st Batch of VI form (SSLC) students appeared for their Public examination conducted by the erstwhile Madras Government in the year 1948 -49.

The Rosario High School is located in the locality of Pandeshwar, about 2 kilometres (1.2 mi) from Hampankatta, at the heart of the city of Mangalore in India.
