The houses were often named and decorated with accompanying themes. The influence of organic and natural sources is particularly evident in the themes and names of the Art Nouveau homes: "The Sunflower", "The Rose", "The Tulip", etc. Houses also referenced local history or the names of the streets upon which they stand. The Lion of Flanders prominently adorns Cogels-Osylei 2–4, while across the street an entire complex is devoted to Charlemagne. Some street names refer to the independence war of linguistic affinity, the Boer war in South Africa: "Pretoriastraat", "Transvaalstraat"  and "Krugerstraat". On Waterloostraat  houses recall the eponymous battle. One of them, Waterloostraat 30, is adorned with a silhouette of Napoleon in his characteristic headgear, while another is decorated with glazed ceramic panels depicting scenes from that battle. The façade of no. 11, "The Battle of Waterloo", shows the portraits of Wellington and Napoleon, the two great commanders of the age. Bayonets, flags, smoking cannons and drums show you clearly the subject of the house.
