Here are a couple more images of places in my Robt Hale Ltd book 'Coming Home.' The first is the hill above Oporto (Porto) where the English/Portuguese heroine, Juliana, walked in her attempt to book a berth on a ship sailing for England. The Douro River flows down to the sea and Juliana walked beside the river for part of the way.
I saw the Douro five years ago and let me tell you, it is a very impressive river, no mere trickle in spite of the arid inland of Portugal.
The second image is the docklands of Porto, still unchanged today. This is where Colly booked them a passage together and where they sailed from.
