Visited two of the oldest libraries in Europe today what we could only see from far but not go inside. One of them was well worth the trip with guided tour that ended with roof access to views of Prague while the other was just a money grab, though library itself was spectacular to look at. The first pic is Klementinum library which still exists in same state since 1700s while the second and third pic is from Strahov library which also exists since around same time and houses some of the oldest books around. klementinum was totally worth it for the guided tour but Strahov looks more impressive with double libraries.
