I think you are referring to the two round or oval towers just across from the convention center. They are black or very dark brown.

If I remember correctly, a single penthouse unit sold for $1.5 mil (which was big money in the 1980’s) and the guy had a private entrance and elevator up to his unit. The rest of the tower (towers?) was empty.

I’m hoping that many of the condo projects currently planned for downtown don’t get built. It appears to me that the market is more than saturated already and there are still several thousand units to be built.
