7 Abandoned Wonders of the United States (Part One)

Previously, I published the 7 abandoned wonders of Europe, and this time I will introduce the 7 abandoned wonders of the United States, divided into two parts, with 7 places introduced in each part. In fact, these are the 14 major abandoned wonders of the United States. These abandoned buildings were all very famous in their respective eras, such as the world's first automobile assembly line, the largest brewery in the United States... and so on. But today, the glory has become a part of history.
