Unusual Libraries

Sandro Penna Library

That is not an alien ship you are staring at. It is not a pink bubble gum candy designed by hello kitty, either! That is a house of books providing library services for the people of Perugia, Italy. The public library is named after the poet Sandro Penna. It features rose-coloured glass walls designed to let sunlight in during daytime, and at night, it creates a rare glow. The architect who designed it, Italo Rota, made the three-story disc to exude an appearance of an alien flying saucer.
