During the Nazi period the Germans owned a house in the Terenure/Rathfarnham area. It is in the shape of a swastica. It still exists.
People never believe me when I tell them this.
Can you help me prove I'm not insane?

Maybe you live in the Terenure/Rathfarnham area.
Kind of non-interesting thing I found on Google Earth. The picture of Booterstown in Co. Dublin (beside Blackrock) was taken when the circus was there (look near the sea, between the parks.)
