Picture of a cylindrical multi-level parking garage

Quick answer：

A cylindrical multi-level parking garage is a type of parking structure with a design that features circular or rounded shapes. These garages are designed to optimize space and are often used in urban areas where land is scarce. They consist of multiple levels, connected by ramps and elevators. The circular design allows for a more compact layout and efficient use of space, maximizing the number of parking spaces in a limited area.
