Castle de Essenbergh Ghost Picture

Belinda Berendsen sent us this ghost picture which looks to have a lady in the window behind them. The Castle de Essenbergh has a long history, being from the 1600s...is it a ghost? You decide...

"These picture's were taken at our wedding day. The location was Castle de Essenburgh in Holland. The castle is from the early 1600s. I put a circle around the face and the body. In the window stands somebody...there was nobody else here during the taking of the picture."
