How often do you get to walk inside a stunning Milwaukee mansion? Unless you own one or are looking to buy one -- or get the invite to a bougie dinner party -- it's probably pretty rare.
But on Milwaukee's East Side, a gorgeous Italianate mansion is open to the public. And almost every surface inside is covered in art.
This week on Urban Spelunking, we visit the David Barnett Gallery on Prospect Avenue.
Pharmaceutical magnate Henry Button built the home in 1875 for $30,000, seven years after he "made the Sentinel's list of the 48 most prosperous men in the city," writes OnMilwaukee's Bobby Tanzilo. He lived there until his death.
Fast forward about a century, the home became vacant in 1985. That's when it was acquired by art dealer David Barnett, and the work began to create a gallery inside.
Now every wall and nook is adorned with art -- from paintings, to sculpture, to photography.
Take a look inside, and be sure to visit OnMilwaukee to read Bobby's complete story.

The home is packed with art, on every floor and in a variety of styles. 
Original details are preserved on every floor.
