Located along a red cobblestone street lined with vintage green lanterns, The Treasury sits on a corner block in the heart of downtown with windows facing south & west to allow a ton of natural light into our space from morning to evening. 


Delavan is truly a hidden gem to those who haven't visited. Downtown boasts cool old buildings, ivy walls, painted brick murals showcasing the city's history, beautiful lush parks, churches, and lakes - all in close proximity to our space too!  The entire downtown block is recognized on the national historical registry and boasts unique ornate architecture every direction you look along with antique stores, historically well-known shops, restaurants, and other locally owned businesses.  


A little bit of history about Delavan is that it was previously a bustling circus town where The P.T. Barnum Circus, “The Greatest Show On Earth”, was founded in 1871.  While you're here check out the historical society and the murals painted around town!


As an added perk, all street parking is free and open to public use along with various large municipal parking lots along the same block as The Treasury.  The building is close to major interstates and popular vacation destination, Lake Geneva.  Downtown Delavan is an easy drive from major cities Milwaukee, Madison, and Chicago to name a few!
