Rue François Fauré
On both the houses in this sketch you can see the 'génoises' which are a common architectural feature on old houses here in Languedoc Roussillon and other parts of southern France. These are single, double or even triple rows of canal tiles fitted under the eaves and filled in with mortar. Their purpose, I've learned, is to protect the walls of the building from rainwater, in the absence of guttering. The taller the house, the more rows of 'génoises' are needed to do the job.
Line and wash with a bit of coloured pencil work at the end.
