The Temple of Human Passions (French: Pavillon des passions humaines, Dutch: Tempel van de menselijke driften), also known as Pavillon Horta-Lambeaux, is a neoclassical pavilion in the form of a Greek temple that was built by Victor Horta in 1896 in the Cinquantenaire Park of Brussels. Although classical in appearance, the building shows the first steps of the young Victor Horta towards Art Nouveau. It was designed to serve as a permanent showcase for a large marble relief "Human Passions" by Jef Lambeaux.
