The main attraction in the city of Granada is the Alhambra... an Islamic Palace built on a hill overlooking the city. The history of the Alhambra goes back to the 9th century, although most of the current structures were built between the 14th to 16th centuries.
My father had visited the Alhambra in November of 1954, and had taken two photos, both of which we were trying to match up.
