I found this museum by mistake. This museum offers 40 art murals that were creates by 70 artists,…read morelocals and internationals. It's about 4,000 m2 of art. The walls where the murals were painted are the residential walls of apartment projects. All murals are maintained in excellent conditions, also the fact this museum is located in San Miguel, a neighborhood that is not a "turtists"center is even more interesting to visit. You will be amazed by the power these walls make you feel. When you are in front of them seeing them with your own eyes you understand how important is to promote art in low income neighborhoods, this museum is a jewel hidden in SanMiguel and I strongly recommend you as a tourist and locals to visit them and appreciate this hard work. I am so happy I made this review and listed in Yelp "Museo A Cielo Abierto". Give the empty walls to artists and communities so they express dreams, their POV. Art makes neighborhoods beautiful, helps local economy. Better hrs to go and visit Morning, afternoons. Avoid going at night. Also the murals have public lighting at night, but for safety reasons better go in daylight.
