The Leeds Corn Exchange is architect Cuthbert Brodrick's masterpiece, a complete oval rotunda topped with a glazed elliptical dome, built in 1864 for grain trading and now occupied by independent retailers and street food vendors on two levels. The building's proportions are extraordinary, and the dome floods the interior with light in a way that makes everything inside look better than it deserves.
It sits in the Call Lane area, adjacent to the Shambles, and is free to enter. Even if you don't buy anything, the interior is worth standing in for five minutes. The street food floor upstairs changes traders regularly.
