Medellín Museum of Modern Art

[Riobard]

Enjoyable though modest in collection size, and not a big time commitment. Nice little café. Not in a cluster of other sites, so a separate kind of activity, but was walkable from Poblado accommodations several blocks south. View of Olaya Herrera airport space to west, from rooftop. If you guessed the courtyard scene is a flash mob rock-paper-scizzors tournament you are likely correct.

They have a great movie theater as well and on weekends play free movies outside on a large screen and that grassy area and steps are packed with people…
