18. Urban Light by Chris Burden, 2008
Since the installation of Burden's Urban Light at LACMA in 2008, the work has become an easily recognizable landmark of the museum. Burden began collecting streetlamps from the 1920s and 1930s beginning in 2000. Eventually, Burden's collection became Urban Light, an assemblage piece of 202 restored streetlamps that brought a new feeling of illumination to LACMA's Wilshire Boulevard facade. As long as it is there, and even when it's not, the piece will be remembered as transformative and beautifying, even as it exists outside the museum itself.
