The Royal Palace was built, as commanded by the House of Medici, in the late 16th century, and became the National Museum in 1989. Today, it hosts numerous paintings, sculpture, tapestries and decorative art pieces that belong to the courts of the city government, such as the Medici, Lorena and Savoia, as well as some private collections. The building still has the appearance of an aristocratic residence, with fittings and furniture from the 17th to 19th centuries.

The Old Wastewater Treatment Plant, operational from 1906 to 1967, now showcases the evolution of architecture, technology and water management. It was a key part of Prague's modern sewer system, designed to collect and treat wastewater before discharging it into the Vltava river, significantly improving public health and aiding the city's development. Today, the site, managed by Tovarna z.ú., hosts exhibitions, concerts and themed events, featuring operational steam engines and showcasing the original machinery and craftsmanship. The plant is a National Cultural Monument of the Czech Republic, an anchor point of the European Route of Industrial Heritage, and a UNESCO candidate.

The Hofgarten is the green lung of Düsseldorf. It stretches from the Jacobistraße with Schloss Jägerhof and the bordering Malkasten Park to the Heinrich-Heine-Allee by the Altstadt (Old Town) and from the Königsallee to the Rheinterrasse (Rhine Terrace) on the banks of the Rhine. Because of its diversity and the pleasing contrast between nature and formal design, it is a popular destination for relaxing walks.
