Tywyn Primary School is a 1950s built school located in Aberavon. Built in 1954-55 by A. N. Coles Ltd. (Cardiff) to the designs of Stephen Thomas, Chartered Architect of Newport, in collaboration with Glamorgan County Architect's Department under E. A. E. Evans at a cost of £135,000, the school consisted of a three-form entry junior and infants' department. Tywyn Primary School was the second primary school built in the Sandfields area of Port Talbot, necessitated by the expansion of the Steel Company of Wales in Port Talbot and the development of the extensive housing programme in the Sandfields area. Upon completion the school could accommodate 840 pupils - 360 infants and 480 juniors - with nine ground floor classrooms in the infants' department and twelve classrooms in the junior department. The junior department consisted of two double storied wings linked by staff accommodation, one wing having eight classrooms and the other having four. An assembly hall was provided for both departments, linked together by a dining hall which served both departments.

When the school was designed, the licensing of steel was in force under Government control and to reduce the amount of steelwork required, most of the structural work was carried out in brickwork, with brick piers supporting the steel joists which carried the asbestos flat roofs. Perforated steel beams were used to support the flat roofs resulting, according to the County Architect, 'in a most decorative and pleasing effect'.

In 2018 there were 454 pupils on roll at Tywyn Primary School, including 80 part-time nursery pupils, in 14 single-year classes and one mixed-year class. Under Welsh Government's Sustainable Communities for Learning Programme (Band C of 21st Century Schools Programme), plans have been approved for a replacement 3-11 primary school where a new build school would be built on the playing fields of the existing site, and the existing building demolished to make way for new playing fields on completion.
