The point you raise is an interesting one and now that you mention it, no, we're not sure, although we don't think so.
While it may have come as a surprise to learn that the Las Vegas Strip is home to one Hindu shrine, it's even more amazing that the one still residing at Caesars was actually predated by a much earlier and less explicable Indian temple. Here's how that strange tale goes, so far as we could ascertain.
In 1904, the British had a two-story, 35-foot-high, 14-ton teakwood replica of one of the sacred white-marble Jain temples of Palitana in the Gujarat province of India constructed for the 1904-05 World's Fair in St. Louis, Missouri. For reasons that remain a mystery, this wooden replica, which was meant to be returned to India, somehow ended up in the hands of none other than eccentric billionaire Howard Hughes, although as far as we know he hadn't even visited the expo and there were no practitioners of the Jain faith (whose followers believe that all living things have a soul and preach benevolence toward all forms of life) in the U.S. at that time.
In either 1969 or 1970 (accounts vary), Hughes purchased the Castaways as part of his Las Vegas casino-buying spree. This was the Castaways built on the Strip in 1963 on the site of what was formerly the Sans Souci Hotel and prior to that the Red Rooster Nite Club, not to be confused with Showboat casino on E. Fremont Street that was renamed the Castaways in 2000 and imploded in 2005. Before Hughes bought it, the original Castaways' principal claim to fame was a 16,000-gallon aquarium in the hotel bar that contained no fish, but rather a naked showgirl, who'd swim around underwater in it three times a day.
After Hughes purchased the property, which had been suffering from ongoing financial woes, for $3 million, the so-called "Gateway to Luck" temple, which its new owner put on display in the parking lot, became its chief attraction. There it remained, so far as we can tell, until Howard Hughes' death in 1976.
The confusion and controversies surrounding the will and estate of the deceased recluse are well-documented, and although Steve Wynn didn't purchase the Castaways (on the site of which he built the Mirage, which is home, among other things, to an aquarium with real fish in it) from the Hughes Tool Co. until 1987, we're not sure who presided over the property in the interim. All we could find about the fate of the temple was that after Hughes passed away, a delegation of Jains, who had begun emigrating in numbers to the United States from the early '70s, requested that the Hughes' corporation donate the temple to them. This evidently they did, we think some time in the '70s, and the temple has recently been reassembled as part of the Jain Center of Southern California, located at 8072 Commonwealth Ave., Buena Park, where you can see it today.
