The Carthusian Order
The style of the Carthusian life, that is a solitary lifestyle tempered by community, is reflected from what can be seen on the outside, in terms of the buildings. You will consequently find all Charterhouses to have three main parts :
There are the "Major" Charterhouses (like the Grande Chartreuse, over 30 cells, who construction dates back to the 17th century) and "Lesser" Charterhouses (like the Chartreuse de Portes, in the French region department of Ain, which has maintained the aspects of a primitive Charterhouse, with its 12 cells surrounding the cemetery.)
