From Lego -
"Discover the first-ever museum to join the Modular Buildings collection. Home to an array of brick-built exhibits it features dual skylights that allow light to permeate the building’s 2 levels, illuminating the towering brachiosaurus skeleton and collection of treasures within."
This set is very large like the other #lego Icons sets. However there is functionality with what you can display, they (lego) just held a contest over the lego ideas website to see what people could of made to add into their museum exhibits. I would love to hear what you would put in your lego city museum down in the comments!
