Bertone is from the town of Romano Canavese, here are two photos from the town's website:
I dont think they are the same tower, one is supposed to be outside the town on a hill, the other one looks like it is part of the town.
This is thier coat or arms
According to the thier history page:
In the fourteenth century Romano was also involved in the Tuchini Rebellion, a rebellion by the peasants harassed by nobles which is also remembered
in the historic Carnival of Ivrea. During these dramatic events, the castle was destroyed and only one tower remained intact, this tower is still a
symbol of the town. Throughout the Middle Ages the jurisdiction of the territory of the Romano was a source of conflict between the bishop of Ivrea
and Savoy. Some of the most powerful noble families were the Orengiano and counts of San Martino.
The Tower, which is isolated on a moraine hill*, is the symbol of Romano Canavese.
It dates back to the thirteenth century, is mentioned in the statutes of Romano in 1315: in case of danger the men of the village were called with
Measuring 5.50 x 5.40 meters at the base and the height is 27 meters. Originally the tower was equipped with battlements and was about 25 meters high.
In a painting dating from around 1800, you can see the original structure before it was remodeled in to a belfry.
The tower is built of brick and has no decorations. The walls have a thickness of 1.60 meters at the base and are composed of an external face and an
inner, thick 20-25 cm each, the inner cavity is filled with stones and pieces of brick, mixed with mortar.
The ancient access door is currently six meters from the ground level, it was accessed by a wooden ladder or rope, removable in case of danger.
On the wall to the west tower has a deep fissure, caused by lightning May 5, 1890.
Town or Romano Canavese (Italian site)
*A moraine is any glacially formed accumulation of unconsolidated glacial debris (soil and rock).
So my guess is that the tower is on his coat of arms to announce where he was born, i.e. it is a very important part of who he is, he wanted everyone
to know that he was from the town of Romano.
Also interesting to note, the Italian word for moraine is moreno, which could also mean Moorish. So a tower with its foundations in the Moorish empire
(or Islam). So maybe the rebuilt church will have some stronger Islamic ties.... or interfaith.
Does anyone see anything more in the crack caused by lightning?
One last thing to note, even if he isnt elected pope this time, there might still be time for him after the next one is dead. Also I think the fact
that Ratzinger resigned rather than died in the job makes him a false pope, he was never really pope so he isnt the 111th of Malarchy's prophecy but
the next one will be.
