The best place to start your visit to Colmar is in the medieval old town. This historic part of Colmar Old Town has various interesting areas such as:
the part of the old town described as 'Petite Venise' is especially attractive, with lovely houses along the river banks
the Rue de Tanneurs (Tanners Street) with very tall houses where they once stretched pelts
the Quai de la Poissonnerie (Quai of the fishermen)
the 14th century Ancient Customs House with magnificent stained glass windows and a roof decorated with colored tiles
While the great appeal of the old town is simply in strolling around enjoying its overall charm, there are also a good number of individual buildings of great interest to see as you explore.
