"Biblioteca Nacional One of the more jarring building styles you’ll find in the city’s architectural mishmash is brutalism, and Argentina’s National Library is an iconic example of the movement. The imposing structure rises like a mammoth tree in the park that surrounds it, and its design seeks to suggest expansion: A root-like system of underground book depositories can be enlarged without changing the building’s intended aspect. When readers request titles, these come up through the building’s central trunk to a fifth-floor reading room, open to the public and featuring an unobstructed view of the Recoleta neighborhood and the river. Check the library’s website for information on talks, concerts, and events. By Travesías"
