In the first photo, the yellow arrow indicates the golden roof of the National Theatre. When you come over the bridge, you`ll be in Újezd. At the base of Petřín, exactly where the lower station of the cableway is. Across the street from the cableway station is Angelato, the ice cream parlor. They make yummy ice cream there, including this one mint ice cream with chocolate.
And if you have a good day, you will maybe meet a lubrication tram there. The tram oils the tracks to reduce the annoying whistling and noise of tram traffic, especially in the curves of the tracks. And do you know what it means, to see a lubrication tram? That you will be lucky that day.
