White Castle No. 3, located on the northwest corner of Fort Wayne Avenue and Delaware Street, is the nation’s third-oldest surviving White Castle building. The small castle-shaped brick building, and hundreds of others across the country, primarily served small, inexpensive burgers known as “sliders” because the grease helps the love-em or hate-em burgers glide down the throat. Just two years before the Great Depression, this store opened  a wee bit smaller than seen here. Within a few years an addition was added to the back. Located just south of an Indianapolis Public School (Benjamin Harrison No. 2), former students recall that it was torture sitting in class with the smell of onions and burgers wafting in through the open windows.
