When visiting Bauduen, you will see some andrones, some still "caladées".
"Androuna is an Occitan word that originally meant a small passage between two houses. Later also a lane or a cul-de-sac."(Wikipedia)
"In Provence, the androne is a stepped street that can be covered by houses. It is quite common to find some in Haute Provence, such as in Sisteron or Forcalquier, where the poet Paul Arène (1843-1896) said: "These were the cutlery, precious shelters to polish the rainy days".
