Yes, we can add the name but I’d like to be sure.  Maybe you can help.

Isn’t it rather "Héliport IV"?

(Apparently, this name goes for every language—there does not seem to be Dutch translation—and we should probably do the same for buildings I, II and III nearby.)

Feel free to comment below if you can confirm this.  And then we will update the map.
