Whether and how to cite a traveling art installation depends on how you refer to it in your paper. If you mention it in passing, no citation is needed. If you discuss it in detail, you need to cite the source where you found the information—for example, a website that discusses the installation or the installation at a specific location. 

The following shows an example of a works-cited-list entry for a website about an art installation:

Walking with Our Sisters, 2019, walkingwithoursisters.ca/.
