Industrial Treasures is an antique and vintage store in St. Charles, Illinois, offering a large, continually changing collection of industrial antiques, architectural salvage, furniture, lighting, artwork, and distinctive collectibles. Located at 1501 Indiana Avenue, the shop welcomes both local residents and visitors, with in-person browsing recommended because many items sell before they are listed online. The business is operated by the owners who founded Dewell & Dewell, a Fox Valley industrial equipment business that served the area for more than 35 years.

Its industrial collection includes factory lighting, tools, machinery, and reclaimed materials, alongside vintage and antique furniture, original artwork, signs, books, toys, home décor, and unusual curiosities. The store also features handcrafted artisan products and work by artists including Carl Hayano. Its varied inventory ranges from practical equipment and architectural pieces to one-of-a-kind decorative finds. Industrial Treasures sells selected products through its online store, offers gift certificates, and buys vintage and antique items. The shop is open Tuesday through Saturday and Sunday, and closed Mondays.
