‘Trier hates you,’ reads the graffiti outside the Karl-Marx-Wohnhaus in Trier. Actually, that’s a bit unfair. Trier doesn’t hate Marx, but it’s always had mixed feelings about its most famous son. Marx’s 200th birthday will be marked by several lavish exhibitions in Trier, which is ironic, for this quaint Rhineland city has never known quite what to make of the author of Das Kapital.
