When it reopens its doors July 1, the National Museum of Mexican Art will be kicking off operations with a major financial boost after it received an $8 million donation from philanthropist MacKenzie Scott.

Attendance was down 30 percent last year at the museum, largely due to its hugely popular retrospective of David Bowie's career–the museum's most-attended exhibition ever. Most other Chicago museums fared better, according to 2015 attendance data compiled by Museums in the Park.

This year’s free exhibit–the largest of its kind in the country–features 116 pieces of artwork from more than 90 artists and offers an inside look at some of the traditions of the holiday.
