“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.
Expect persecution.
