An interesting building. It is now a research-only library, but you are allowed to gain access as a visitor (show a copy of your passport). Once inside, there is an area before the researchers only point where you can admire the portraits and several important books in cases. Worth a look as you are leaving the Museum of Archaeology, which is about 5 minutes away. There are a few cafes outside where you can sit under parasols and enjoy drinks, snacks or full meals.
