Discover A Historic Brewery Turned Treasure Trove At This Massive 3-Floor Antique Mall In Winona

Published: July 8, 2025

What started as Peter Bub’s Brewery in 1862 has transformed into one of Minnesota’s most captivating antique destinations.

Treasures Under Sugar Loaf occupies the historic former Sugar Loaf Brewery building, which includes storage caves dug into the bluff and dates from 1872 when the original building was destroyed by fire and a replacement built.

This isn’t your typical antique store experience—you’re literally shopping inside a piece of brewing history that once produced beer until 1969, complete with mysterious cave tunnels that extend 130 feet into Sugar Loaf bluff.

The three-story building houses over 60 knowledgeable antiques and collectibles dealers, creating a treasure-hunting paradise where new items arrive daily. You’ll find yourself wandering through the same spaces where brewers once stored their beer in cool limestone caves, now filled with everything from ancient artifacts to handcrafted local art.

Mysterious Elements: The property still holds mysteries, including ventilation shafts that open somewhere on the bluff above, and cave areas that showcase the building’s fascinating brewing past.

Practical Considerations & Visitor Tips

I love writing and I love Minneapolis! My favorite places to explore are charming small towns, vibrant arts scene, and hidden gems anywhere outdoors. Fall foliage with a good documentary is my version of heaven.
