Sonop has a first-class archive housing a collection of memorabilia and photographs covering the past 100 years. In Sonop's archive one truly gets the feeling that one is part of something big by being a Sonop resident.

Apart from these cultural activities organised and monitored by UP, there are many other Sonop cultural activities, such as the Informal, Dinners, Regional Functions and Internal House Days that are attended by Sonop residents only. In addition, Sonop also organises an annual Sonop tour, giving Sonop residents an opportunity to go on holiday together.

Another aspect of Sonop's cultural life that could be mentioned is that the residence has 10 Pierneef paintings that are exhibited on campus.
