The largest antique store in the United States is often considered to be The Antique Market located in Atlanta, Georgia. This expansive store offers a vast selection of antiques, collectibles, vintage furniture, and art, spanning multiple categories and eras. It features thousands of square feet of space filled with unique items from different periods, making it a popular destination for collectors and enthusiasts.
Another notable large antique venue is The Rose Bowl Flea Market & Antique Show in Pasadena, California, which is one of the largest regularly scheduled antique markets, attracting numerous vendors and visitors. However, in terms of a single permanent retail location, The Antique Market in Atlanta is often cited as the largest.
It's worth noting that the title of the "largest" can vary depending on the criteria used, such as total square footage, number of vendors, or inventory size.
