DULUTH — The Tweed Museum of Art in Duluth has received a $1 million donation that will be used to kick off a $4.2 million renovation project.

Chancellor Lendley Black announced the gift Thursday at the museum on the University of Minnesota Duluth campus. He said the money is from the Alice Tweed Tuohy Foundation in Santa Barbara, Calif.

The university said the renovations will add two gallery spaces and improve the building’s visibility by replacing some walls with glass. Construction won’t begin for another year.

Black said the university has more than 9,000 pieces of art. It opened to the public in 1950 out of George and Alice Tweed’s house in Duluth before moving to the university campus eight years later.
