The building is beautiful, but the inside is a gem.
Built at the end of the XIX century, it is one of the most beautiful Athenaeums in Europe.
Now, you can only go inside paying a fee of 10 lei, that are 2 euros, but you can only pay in cash, as in many other places in Bucharest, even in the XXI century.
You can visit the hall in the main floor but also the auditorium as well. And if you are lucky enough as we were, you can see a performance during the rehearsals of the artists.
