My grandparents visited Alghero back in October 1984. They flew into Alghero and then made their way into the city as part of an organised coach trip. They spent most of the time on the beaches of Alghero, but as part of their holiday package, they also had coach trips out to some of the historical sites.
They spent a week in Alghero in the October half-term of 1984, which I found out long after I had visited Sardinia for the first time.
Below are some of their photographs from their trip.
