Welcome to 300 Main. 300 Main is a historic commercial building on the 300 block of Main Street Walhalla, SC, built around 1889. After an extensive renovation by owners Mike and Alisaun Crenshaw in 2020-2021, they opened two new retail spaces downstairs and two short-term luxury apartments upstairs. Come stay in luxury at The Residences, and find the the best shopping at Sunni Ann Mercantile Co., Sunni's Vintage Shop and Sunni's Village Market in our other historic building three doors down. Branch out from there as Walhalla is the perfect place to shop, eat and stay, on the way to the mountains.
