If you have a bit of energy to spare, it is possible to take a detour by the steps of the Montagne de Bueren. This street was built at the end of the 19th century to provide a direct link between the Citadel military site and the city centre. Several decorative elements on the façade of No. 25 reproduce the characteristics of the rippling and organic lines of Art Nouveau: stone lintels, ironwork, coloured chassis and glazing, etc.
The façade of No. 19 especially displays the characteristics of ‘cottage’ architecture, with for example an original oriel window painted red. Also, the metal lintels above the bay windows were designed as decorative elements.
On the other side of the street, the ironwork on the entrance door to No. 28 includes some very pretty Art Nouveau style horse chestnut leaf designs, whilst the rest of the building is eclectic in style.
