The small group of photographers I am in gathered for taking photographs in
Bataria da Arrábida an abandoned fort just a few kilometers from Setubal in the Arrábida mountain.
The sky was very clear and no clouds were on sight. However, at the western area the cloud came up and slowly moved to East. And as it was moving it was also becoming longer and longer vanishing at the same time.
Beneath a glimpse of Setubal can be seen as a large portion of the peninsula in front of the town.
The Peninsula is here framed by the window of an observation position. (Perhaps I will return there to take more photographs in a different time of the day)
The guns are from 1942.
The last but not the least, is just the gun in action as the cloud was vanishing.
