These set of colorful gates are located at the Alameda RTD Light Rail Station. You can see them as you pass by either from the train or a car, but you're probably going to want to take a closer look.
This work of art began as a wood maquette model designed by Herbert Bayer. He died in 1985 at the age of 85, so he didn't build this actual sculpture. Dan Cohen from D4 Urban, which owns the Denver Design Center & commissioned some of Bayer's works from his grand step-daughter, Koko Bayer. She was involved in making sure Herbert Bayer's ideas were exacted.
There are 4 Gates, each painted a different color: yellow, red, white, and the tallest one in signature "Bayer Blue". The tallest gate is 16 feet tall. In a circular perimeter around the gates, there are concrete blocks that serve 2 purposes. One is for seating and the other is to keep maintenance vehicles from getting too close.
Bayer was inspired by asimilar "gates" he saw in Morocco when he created the Four Chromatic Gates. In Santa Barbara, CA, there is a Bayer sculpture called "Chromatic Gate". I saw that one in 2020. It is similar to this one, but has six gates colored in yellow, orange, mauve, red, purple, and lastly the "Bayer Blue" for the tallest gate. It consists of the same type of gates, but they are situated differently than these Four Chromatic Gates.
If you want to see another Bayer sculpture, check out the Articulated Wall that's not far from here. It's visible from I-25. ( https://www.yelp.com/biz_photos/articulated-wall-by-herbert-bayer-denver?select=Axj8CofxWpbRwvs-tsr08w ) read more
