Düsseldorf's Altstadt (Old Town) is also home to some of the city's most beautiful churches. For instance, the Sankt Lambertus Basilika, which was first built in the 13th century, and which with its twisting spire helps make Düsseldorf's skyline unique. In conjunction with the Schlossturm (Castle Tower) and the River Düssel, the basilica remains part of the Old Town's original core. This church's parish altar also houses a shrine containing relics of Saint Apollinaris, the city's patron saint.

Built by the British East India Company in 1640, Fort Saint George is a historic landmark in Chennai which houses the legislative assembly of Tamil Nadu. The fort is a key site showcasing Chennai's colonial history. The fort complex includes The Fort Museum, which displays artefacts related to Chennai's colonial past and a library, which holds historical documents and books.

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. A more profound insight into Düsseldorf’s history can be gained at Stadtmuseum at the corner of Bäckerstraße and Berger Allee. Its cosy garden is treated as an insidertip! The Carlsplatz, and its lively food market open from Monday to Saturday. 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.
