Aerial view showing the relation of the current manor house (the white building with green roof) to the river and chapel. I believe, based on a drawing of the ruins of the previous manor house seen in this article:  <a href="http://genealogiestemarie.ca/data/documents/29_Manoirs-Taschereau_002.pdf">http://genealogiestemarie.ca/data/documents/29_Manoirs-Taschereau_002.pdf</a>  that the manor house Arnold used was probably on the opposite side of the chapel.
