Stendahl's syndrome:

"Italian psychiatrist Dr. Graziella Magherini noticed tourists in Florence were experiencing ``anything from temporary panic attacks to bouts of outright madness.''

She dubbed the condition Stendhal's syndrome, which is defined by wordspy as ``dizziness, panic, paranoia, or madness caused by viewing certain artistic or historical artifacts or by trying to see too many such artifacts in too short a time.''"
