Basel was a major town in the middle ages , a legacy of this is the pretty Old Town . A highlight of a walk round the city is a trip to the Munster and Kunstmuseum . The oldest Roman colony on the Rhine , the site contains a well-preserved theater as well as the remains of a forum , amphitheater and aqueduct . Outside of Basel is the thousand year - old Roman settlement of Forum Nova . The Hasenhorn which run 25 miles east of Basel is also worth a trip .
