The cathedral's design is stunning,the highlights being the sandstone spires and painted wood ceiling.

Carlstadt is the city’s exquisite quarter of galleries and antique shops. Citadellstraße with its elegant stately residences from the 18th and 19th centuries and the flair of its streets almost unchanged since these days, seems to have escaped the passing of time.

From here, take the attractive Bilker Straße for a visit to the Heinrich-Heine- Institute or proceed past the former residence of Robert and Clara Schumann to Bastionstraße, a must for every lover of antiques.
