The word “to wonder” has of course a good sense which we all understand if it means to wonder at a certain state of things to wonder that such & such is the case. It has a good & clear sense to say that I wonder at some unusually dressed man as I have never seen before or at some strange sound etc. etc. It is also clear what it means to wonder at the existence of say a building which you had thought had been pulled down long ago for here it has a meaning to say “I did not think that this building still existed” or to say that it does exist.
