If you take a stroll down Eerste Constantijn Huygensstraat in West, you’ll no doubt spot loads of interesting shops and cafés, but every once in a while don’t forget to look up. High atop the building at number 38, which is home to the Mentrum Psychiatric Clinic, you’ll also see an intriguing work of art created by Russian-American artists Ilya and Emilia Kabakov. The monument depicts a patient on the top rung of an extensive ladder ready to return to the world where he will be looked after by a guardian angel.
