What are some locations that used to be popular among tourists in past generations but is not anymore?

The first place that comes to my mind is Atlantic City. In my parents' generation it used to sorta be like what Vegas is today, but now, almost no one goes there anymore and the town itself has become very rundown and seedy. I went there once when I had just reached drinking age (21 in the USA), and I don't plan on returning again lol

Another one is Acapulco. It used to be the honeymoon capital of North America in the mid-late 20th century, but after some unfortunate events in recent decades, tourists have began going to other places in Mexico for vacation like Cancun, Tulum, Cabo and Playa del Carmen just to name a few.

What are some other places that come to your mind on this?
