Museum of Science and Technology and to Kalemegdan

Hello dear friends!
Tonight I am taking you to the Museum of Science and Technology and to Kalemegdan.
So many beautiful photos, I put them in several collages and I hope you will like them.
The first photos represent Kalemegdan, where there is a fortress, a military museum, the Ružica church, and where you can see the confluence of the Sava and the Danube.
Further, you can see the inscription at the entrance to the museum and the words written by Nikola Tesla in 1900 and only a tenth of the exhibits displayed in the museum of science and technology.
Next is the toy museum and the museum of illusions. There are crooked mirrors, a kaleidoscope, a crooked room and many other interesting exhibition rooms and exhibits.
Indeed, I have visited this museum many times, as well as Kalemegdan, and a good time is always guaranteed.
Have a nice night!
