Quartier du Rôtillon in downtown Lausanne is characterised by its very steep topography. The popular district was created when the Flon river was covered in the 19th century, but some of its buildings started to be abandoned in the early 20th century. In 1994, the city of Lausanne created a new plan for the district and several new buildings were constructed.
Several half human, half animal sculptures by artist Nikola Zaric can be found all throughout the neighbourhood.
Îlot A was designed by Atelier Commun and completed in 2013. It is comprised of four buildings separated by small stairs and a walkway
Îlot B was designed by the architecture practice atelier niv-o and completed in 2014. It is a mixed-use project combining a restaurant, offices and apartments. Its colours are the work of colorist Claude Augsburger.
A mural by Titeuf creator Zep (Philippe Chappuis) was inaugurated in September 2015.
