Nearly 50 years ago an important book about Las Vegas architecture from a theoretical standpoint was published. It is "Learning from Las Vegas," the title inspiring the title of this post.
The Las Vegas of 1968 when the authors visited and did their on-site research was different from today's Las Vegas in some important ways. Nowadays many of the largest casinos offer more than gambling, restaurants and shows. They have shopping areas and themed architecture and interiors. Moreover, the architecture and interiors were created at great expense.
That is in contrast to nearly all the Modernist buildings we see today and that were built since World War 2. Those structures, conforming to the architectural profession's near-universal design religion, are visually comparatively simple and usually nearly or absolutely ornamentation-free. They are also inexpensive to build compared to Las Vegas' grand casino-hotels that include traditional paintings and ornamental sculpting. The latter is far more costly today than it was a century ago when there were many skilled craftsmen who did such work at affordable prices.
What this means is that Las Vegas is one of the few places in America where folks can experience important new buildings featuring what was much more common before the 1930s. The town is an oasis in more ways than one.
