Carthusians are known for being some of the most ascetic of all religious orders, with vows not only of poverty, chastity and obedience, but also of humilty (just an idea of what this entails - they do not publish anything under their names, they are completely cloistered, and they are buried in unmarked graves). But boy do they know how to create beautiful things for the glory of God!! This chapel on the former monastery property (now a museum) is absolutely amazing, with beautiful inlaid marble designs throughout. I cannot even begin to describe the beauty of this church.
