The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.

Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria. At one time the Clementinum was known as the third largest Jesuit college in the world.

The National Library was founded in 1781 and from 1782 the Clementinum was a legal deposit library. In 1918 the newly established Czecho-Slovak state took over the library. Since 1990, it has been the National Library. It contains a collection of Mozartiana, material pertaining to Tycho Brahe and Comenius, as well as historic examples of Czech literature. The architecture is a notable example of Baroque architecture and Clementinum, covering 20,000 square metres, is the second largest complex of buildings in Prague after the Prague Castle.

The oldest weather recording in the area of the Czech lands started in Clementinum in the year 1775. The recording continues through the present day.

The Baroque library hall inside Clementinum is known for its beautiful interior, including ceiling artwork by Jan Hiebl.

Really interesting historical place, especially if you are interested in Astronomy. The guided tour in English was good and we had plenty of time to look around. The library was spectacular! And I didn't expect that we were going to climb all they way up to the tower and get to see the view from the top. It was really cool. I wouldn't recommend this if you are scared of heights and also steep (and old) stairs.

Beautiful museum in the middle of city center. The ticket price was fair and already include tour guide who give excellent explanation. It was complete and clear enough. The library was had beautiful art on the ceiling and designed so well. There's a very beautiful view from the tower. It's worth every penny n every second of your time.

If you're into astronomy and not afraid of stairs you should not miss it. Old time instruments, the most amazing library I've ever seen and great views of the city, specially at sunset.. Worth the 176 narrow steps to reach the top

Beautifly preserved baroque library. Very important information about the place is that you are allowed to see the library through the doors, no pictures allowed. But for those who are there to experience it, it is great place to visit. The tour took around 45 minutes with tour guide, we had amazing views from the astronomical tower. However, to get to the top we had to go through quite narrow stairs, I was scared a bit but it is manageable. We really enjoyed it.

A fantastically persevered peace of history. So much of today's astronomy came from this place. People like Kepler did their work in this place. And the baroque library is definitely the best library i have ever seen. Our tour guide was also fantastic.

Redipuglia World War I Memorial

Redipuglia is the largest Italian Military Sacrarium. It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.

The monumental staircase on which the remains of one hundred thousand fallen soldiers are lined up and which has at its base the monolith of the Duke of Aosta, who was the commanding officer of the third Brigade, and gives an image of a military grouping in the field of a Great Unity with its Commanding Officer at the front. The mortal remains of 100,187 fallen soldiers lie here, 39,857 of them identified and 60,330 unknown.
