Regardless of its history, the Devil’s Den is most famous for being the location where a satanic group performed 2 sacrificial murders. In 1997, the bodies of 2 teenage boys were discovered at Devils Den by local kids.

Considered an eyesore and a symbol of urban blight, the Pro Plus Flour Mills (map) have lied abandoned for decades. Built by Carl Hilmar Guenther and his company C.H. Guenther & Sons, this flour mill was one of the first ones constructed in San Antonio.

Before the completion of the national railroads, the Pro-Plus Flour Mill could only sell their product locally. With trains available to them, they started to ship and sell their flour all across the country.

With the increase in business, the flour mills grew to new heights and decided to modernize their equipment. Old wooden flour mills were replaced with tough 6-story tall stainless steel ones that are still in the mills today.

The future of Pro-Plus Flour Mills is uncertain. Demolition and renovations of the abandoned building in San Antonio have been proposed over the years but no actions have been taken. The abandoned flour mills today serve as an occasional home for squatters, and the homeless.

Once an opulent health spa for the wealthy and famous of San Antonio, over the years the Hot Well Hotel has been reduced to little more than a pile of ruins.

The once luxurious resort opened in 1892 when a nearby medical institution drilled into an aquifer to supply water to a new building.

Accidentally, they discovered a 104-degree well that supposedly had ‘healing powers. The Hot Wells Hotel was opened and was an instant hit. Celebrities, politicians, and wealthy men and women from around the world visited the resort.

It burned down a couple of years after its opening and was rebuilt as a much bigger building.

The resort had swimming pools, a bathhouse, and over 200 lavish guest rooms with several amenities.
