We had a whole town dedicated to this called Radio Kootwijk, in the Netherlands.

It's also long been decommissioned.

In one way I think it's a bad idea because long wave works even when satellites and cables no longer work. It's great for emergencies. On the other hand, the number of people with equipment to receive it is shrinking (even though you can build it with a few components). That of course really hampers its value for emergencies.
