The Lost Mississippi Brew — Decipher the Brewmaster's Secret
You are a diligent historian, in modern-day La Crosse, on the trail of a legendary brewing mystery.
Your quest takes you on a 1.5 km journey, lasting approximately
Uncover the brewing secrets of La Crosse, where the history of beer giants intertwines with the majestic banks of the Mississippi.
The story that haunts this land
Your adventure begins at Riverside Park, La Crosse's first municipal park, opened in 1903. Covering 22 acres along the Mississippi Riverfront, this site was developed in 1926 with baseball fields and tennis courts. It annually hosts Riverfest since 1983, attracting over 125,000 visitors. Your first puzzle awaits you here, immersing you in the city's riverside and festive atmosphere, a prelude to exploring Wisconsin's rich heritage. The initial clues to the Master Brewer's enigma lie within the pathways of this iconic park.
Continue to the La Crosse Public Library - Northside Branch, a historic Beaux-Arts style building constructed in 1904. Listed on the National Register of Historic Places in 1980, this library is a gift from philanthropist Andrew Carnegie, intended to promote public education. With its 10,000 square feet and initial collection of 8,000 volumes, it holds crucial clues. By deciphering its architectural symbols and exploring local legends, you will advance in the quest for the forgotten recipe, connecting the thirst for knowledge with brewing ingenuity.
Your journey then takes you to the Pump House Regional Arts Center, a former pumping station built in 1882 by the La Crosse Water Power Company. Transformed into an arts center in 1977, this 5-story brick building, with its original 20-foot diameter waterwheel, now houses galleries and studios for 50 artists. This National Register of Historic Places site, near the Main Street Historic District, represents La Crosse's industrial transformation and offers a unique perspective on the city's past, a past where water was as essential as malt for brewers.
As you traverse the Main Street Historic District, listed on the National Register in 1994, you'll explore 10 blocks and 120 buildings dating from 1856 to 1930. This historic commercial center, with its Second Empire and Queen Anne architecture, stretches for approximately 1 km, bordering the Mississippi and connecting Riverside Park to downtown. It's a living testament to La Crosse's economic boom. Here, you'll uncover architectural clues and anecdotes about the commercial life that supported the thriving brewing industry, particularly the G. Heileman Brewing Company, a true pillar of the local economy.
The culmination of your exploration will lead you to the former site of the G. Heileman Brewing Company, founded in 1853 by Gottlieb Heileman. This brewery became one of the largest in the USA, producing 2 million barrels annually by 1930. This 20-acre complex, with 1890-1910 buildings listed on the National Register in 1985, produced beers like Old Style and Special Export. Although closed in 1996 after acquisition, its legacy endures, notably with the World's Largest Six-Pack, six 48-foot-tall tanks painted in 1969 to resemble City Brewery cans, located a 5-minute walk from Riverside Park via Main Street. It is here that the Master Brewer's secret will finally be revealed, completing your journey on the Brewery History Trail of La Crosse, Wisconsin.
