5 Best Sights in Düsseldorf, The Rhineland

This stylish, revamped harbor district is a mix of late-19th-century warehouses and ultramodern towers housing restaurants, bars, hotels, and the many media companies that have made this area their home. On the riverbank you'll find the Frank Gehry–designed Neuer Zollhof, a particularly striking ensemble of three organic-looking high-rises. The best way to tackle the buzzing architecture is to take a stroll down the promenade and over the pedestrian Living Bridge, which connects both sides of the harbor.

The oldest remaining parts of the Hofgarten date back to 1769, when it was transformed into Germany's first public park. The promenade leading to what was once a hunting palace, Schloss Jägerhof, was all the rage in late-18th-century Düsseldorf before the park was largely destroyed by Napoléon's troops. Today it's an oasis of greenery in the heart of downtown.

A 25-minute ride on the U79 from the City Center puts you in this historic corner of Düsseldorf, reminiscent of a storybook German town with its winding cobblestone streets and neatly packed stone and brick buildings. Don't miss seeing the crumbling ruins of Kaiserpfalz, a 12th-century castle on the banks of the Rhine.

The Kö-Bogen II office complex bills itself as having Europe's largest green façade, with eight kilometers of green hedges and approximately 30,000 plants in total.

This Gothic church is near the palace tower on Carlsplatz. Its spire became distorted because unseasoned wood was used in its construction. The Vatican elevated the 14th-century brick church to a basilica minor (small cathedral) in 1974 in recognition of its role in church history. Built in the 13th century, with additions from 1394, St. Lambertus contains the tomb of William the Rich and a graceful late-Gothic tabernacle.
