The building has three floors above the quadrangle, with the section below devoted to the primary section. Each standard has four divisions, located adjacent to each other. There is a large hall, a staff room, a gymnasium, three laboratories, and the largest school library in Goa – all surrounding the quadrangle, overlooked by the statue of St.
Ignatius of Loyola, the school's patron saint. The basketball court hosts inter-school, taluka-level, zonal level, and statewide games. The soccer field is situated outside the main campus, and is known as the Loyola Grounds. The old Loyola Ground is being renovated and a football (soccer) stadium built. The main school building was formerly L-shaped, with the longer arm containing the main school and the shorter arm containing the boarding and resident priests' quarters on the upper floors, the Chapel of St. Ignatius and the administrative offices on the upper ground floor with a bridge leading to the quadrangle, and the primary section on the lower ground floor. The new school building is G-shaped, with the new sections housing a hall, library, staff room, gymnasium, laboratories, toilet complex, computer room, and classrooms. In 1993, Loyola High School became the first public school in southwest India to replace black boards with green-boards. The quadrangle, which is used for morning student and staff assemblies, flag hoisting, student concerts, and school fetes, is surrounded by colourful flowering creepers growing on the walls of the school building. The quadrangle is home for South Goa's best-attended English services for Maundy Thursday, Good Friday, Easter, Christmas, and New Years, when scores of people participate accompanied by school choirs. In 2016 the school "won a national-level ‘White Swan Award’ hosted by
AsiaOne Magazine as being the ‘Most Influential Brand’ in the education category in India." ==History==
