St Rita's College was founded by two Presentation Sisters, Sister Alice Kennedy and Sister Mary Madden, and was established as a kindergarten through to senior school on 27 September 1926. The initial enrolment consisted of 16 students with kindergarten - grade 3 being co-educational and grade 4 - senior girls only. Boarders were accepted from all grades. By 1960 the primary school grades of St Rita's had been transferred to St Agatha's Primary School on the adjacent site. By 1970 St Rita's College no longer offered a boarding facility to its students.

The pool itself is inlaid with a stain glass rose. In the beautiful landscaped gardens rests one of the blocks from the old pool.
