Main building The main building was designed in 1929 by Francis Jones and
Percy Worthington. In keeping with the style of Oxbridge, it features a quadrangle and a grandiose Memorial Hall. Entrance to the quad is by a tripartite arch under a clock tower cupola. There is also the Paton Library (named after J. L. Paton, a former High Master), MGS Archive Room (formerly the Alan Garner Junior Library, which has since become part of the Paton Library), Common Room, Refectory, Medical Centre, Book Shop, Gymnasium and Swimming Pool. This is in addition to classrooms (subjects taught in this building are Art and Design, Mathematics, Economics, Classical Civilisation, Computing, Greek, History, Latin, Religion and Philosophy) and administrative offices. The main building also houses the Parker Art Hall which is a three-storey arts studio, situated in the south side of the main building. It is named after former High Master J. G. Parker. It includes a ceramics department with two kilns on the ground floor and also a dark room for photography. Since opening in 1931 the site at Fallowfield has seen many additions to the accommodation as indicated below.
Mason building This is the school's language department, named after P. G. Mason, a former High Master, during whose tenure the building was erected. On the ground floor there are the Language Labs, two suites of listening stations, mainly used to practise the listening parts of national exams. This building was originally the school's Sixth Form block, with construction beginning in 1965. The foundation stone was laid by
The Queen on the occasion of her visit in 1965. By 1970 the shoddiness of the workmanship and materials used was revealed by the cracks which had already started appearing in the internal walls. It is joined to the main building on the ground floor by the Paton Library.
Marks building Named after former pupil
Simon Marks, son of Michael Marks, founder of the
Marks & Spencer empire. It is just west of the main building, and was erected in 1958. Major extensions were made by addition of the first floor (after a gift of £50,000 from Lord Marks) and the
Israel Sieff Lecture Theatre (after a gift of £5,000 from Lord Marks' brother-in-law), which were opened on 19 September 1962. It currently hosts the following departments: Physics, General Science (taken by Year 7 and 8 pupils – before the subject splits into the usual three divisions), Geography, Computing and Mathematics. There are five physics laboratories, including one for radioactive experimentation, on the ground floor. The main computer room is on the first floor of the Marks building.
Theatres and drama Sieff Theatre is named after former pupil,
Israel Sieff, is situated at the end of the Marks Building and was refurbished in 2006; it is used for lectures and assemblies, as well as being the venue to Muslim Friday prayers. The MGS Theatre has recently undergone extensive rebuilding, to provide a modern and comfortable auditorium, together with studios for rehearsals and drama teaching. The Drama Centre Campaign is chaired by Sir
Nicholas Hytner (Director of the National Theatre and a former pupil) who brought
Alan Bennett and the actors from
The History Boys to launch the campaign in 2006.
Sports hall and rectory building The Michael Atherton Sports Hall was opened by
Mike Atherton (a former pupil) in 1997 and subsequently used by the BBC Philharmonic Orchestra in recording of a live CD. The sports hall was severely damaged in a gale in February 2014 and had to be demolished. There are also 2 squash courts adjacent to the sports hall. The former rectory of St James's Birch-in-Rusholme (the adjacent redundant church) is located near the Sports Hall, and is the home of the Biology Department. However, only A-level biology is taught there. A new sports hall was opened in 2016.
Music school Located at the rear of the school, it is the building where the music department is based. There is a music library in the basement as well as a dozen or so music practice rooms, each having a piano, used for private lessons. It contains a keyboard suite allowing first and second years to learn basic keyboard playing and a hall on the west side used primarily for orchestra rehearsals. The original part of the building where the practice rooms are now located had been used in the 1950s and '60s as a bicycle shed.
Junior School buildings In September 2008, MGS opened a Junior School for pupils in Years 5 and 6, extended to Years 3 and 4 in September 2011. Boys entering the Junior School do not sit an entrance exam but attend an assessment day and gain automatic admission into Year 7. The Junior School buildings are both state-of-the-art timber buildings, constructed from sustainable materials imported from
Estonia. Junior School pupils in Years 3, 4 and most of Year 5 are located in Plessyngton Lodge. Year 6 and one class of year 5 pupils work in Bexwyke Lodge.
Outdoor Study and Pursuits Centres The school owns the '''Owls' Nest''', a large hut situated in
Disley, south of Manchester, near to
Lyme Park. The original ex-Army hut was opened at Christmas 1920, but it was destroyed by a
German bomb on 23 December 1940, and a replacement was provided in 1950. The building is used by forms and activity groups of the school as a base for outdoor trips and camping expeditions. ==Curriculum and attainment==
