The old centre of Colmar, a fifty-minute train ride south of Strasbourg and lying east of the main Route des Vins villages, is echt Alsatian, with crooked half-timbered and painted houses. Its small canals and picturesque narrow streets are a flaneur’s paradise. This is prime Elsässisch-speaking country, a German dialect known to philologists as Alemannic, which has waxed and waned during the province’s chequered history. As the proud home of Mathias Grünewald’s magnificent Issenheim altarpiece, the town is a magnet for tourists all year round.
