A circa-1918 physical layout of the ARCADE, which was a mixed-use complex before the term had even been thought of. The core of the structure, indicated in black, was built between 1902 and 1907. Structures such as the Commercial Building and Miami Savings Bank Building came along a bit later.

In a 1920s-vintage postcard view, we see the 50-stall Food Market. It occupied the ground floor of the ARCADE Rotunda.
