Towards the end of the Great Depression, the Johnsons retired to Hollywood and often visited the Castle, which had become a popular hotel and tourist attraction due to the fame of Death Valley Scotty. Thousands of tourists, along with Hollywood movie stars and reporters from around the country, flocked to the Castle each year to see what they thought would be the dwelling of one of the world's richest gold miners.
The Johnsons died in the 1940's, and having no heirs, willed the Castle to a charitable organization called the Gospel Foundation of California. The Foundation continued to run the Castle hotel and tours, and also took care of Scotty, who lived in the Castle the last two years of his life. He died in 1954, and was laid to rest on a hill overlooking the famous home that now bears his name.
In 1970, the Gospel Foundation sold the estate to the National Park Service, whose job is to protect and preserve the Castle for present and future generations to enjoy. Perhaps Death Valley Scotty had that in mind when he proclaimed:
"The Hall of Fame is going up. We're building a Castle that will last at least a thousand years. As long as there's men on earth, likely, these walls will stand here."
