Wikipedia: “Following the establishment of the Association Law of 1901 and its interpretation that effectively banned religious associations en masse, many notable religious institutions across France, including Grand Chartreuse, were closed by the French government.
“While some monks found refuge in Italy until 1929, others settled in the Tarragona region of Spain and relaunched the monastery’s famous liqueur-producing activity. The Grande Chartreuse was sold in 1927 to a group of local entrepreneurs who invited the monks back to their monastery.”
It is from them that we get Grand Chartreuse liqueur, sales of which provide a legacy, and the color. No visitors are allowed inside to this day.
Notice the cat in the second picture. The pictures come from Dr. Josef Ketzer, my tutor in Vienna. "There is a legend that the Chartreux are descended from cats brought to France by Carthusian monks to live in the order's head monastery, the Grande Chartreuse, located in the Chartreuse Mountains north of the city of Grenoble. But in 1972, the Prior of the Grande Chartreuse denied that the monastery's archives held any records of the monks' use of any breed of cat resembling the Chartreux." Wikipedia. Charles de Gaulle owned a Chartreux.
