In early 19th-century Pittsburgh, Pennsylvania the focus was on industry, not dancing. This western city was not yet as sophisticated and polished as Philadelphia which was considered very chic even since colonial times. The aversion to the finer pursuits is evidenced in Jack Turlock’s perspective on the Ballantyne’s ball. One of my editors found Jack’s thoughts particularly funny when he compared being formal with having the flu!
Here is a ballroom/assembly room in Bath, England which I came across in my research and is particularly beautiful. The floor is perfect for dancing!
