Dating back as early as the 13th century, this late medieval building is the oldest remaining parliamentary court still in use today. It was first built as a castle and home to the various counts of Holland, but after several battles for succession, the Binnenhof changed hands many times and, in the process, saw many new administrative buildings erected around it. Extensive renovations are currently underway and not expected to finish before 2028, so politicians have had to find elsewhere to conduct their business. Tours of the surrounding areas are available and more information can be obtained at the Binnenhof Renovation Information Centre, which is right next to the complex.

Sandwiched between the Palatine and Capitoline hills, the Forum Romanum (Roman Forum) is an open-air forum that was once the commercial, political, social, and religious hub of ancient Rome. Throughout the Imperial period, Emperors like Julius Caesar and Augustus expanded the Forum to include temples, statues, monuments, a senate house, and law courts. Today, the Forum Romanum is one of the most visited archaeological sites in the world and offers fascinating insights into Roman civilisation.

In 1996, American artist James Turrell designed the Celestial Vault to showcase the sky in all its glory using an innovative astronomical optical illusion. In the centre of this grassy artificial crater, there is a stone bench on which visitors can lie to observe the sky as a curved dome, emphasising the way light affects how we perceive things and inviting those willing to challenge their own perceptions.
