I got my hands on 3 photos of Luz from the early 20th century, and at first I thought they were almost identical, but in reality you can see the skeleton of Luz developing around 120 years ago.
Here is the first photo, undated other than around 1900.
The one and only place in Luz this photo could have been taken is the top of the mound dug up by Operation Grange in June 2014. Nothing else fits.
There are 3 roads running through this that turn up 100 years later.
The first runs from mid-left to the centre of the photo. That is Rua Vente Cinco de Abril. Except it would not get called that until 1974. Since it was the main road from Burgau in the west, it was probably called Burgau Street. At this point there seems to be one large house and very little else.
Joining up at the central point and heading out to the upper left is current day Rua Direita, heading for Lagos. In this photo, there are no buildings, just trees. Bear in mind we are back in horse and cart days.
Coming from the centre point of the photo to bottom right is Rua Calhete, currently home to the Bull, Kelly’s, Look Steak, Fernando’s, and the Dolphin.
As far as I can tell, very few buildings, the church and the Fortaleza apart, are still standing today. There may actually be one or two, but I am not in the business of checking antique buildings in Luz.
This grainy photo must have been taken a few years later. The posh villa, which was standing on its own on 25 de Abril Street now has a lot of neighbours.
Things have moved on again. There is a new building on 25 de Abril Street. The main road layout of Luz is in place. This photo is clear enough that you can see the trig point on top of the hill.
But please look from the the view at the top of the mound, directly over the Fortaleza, past Rocha Negra to the land sticking out in the distance. That place will return in the 1940s. Just as it did in Panorama 2017.
