Which architectural feature distinguishes a gallerie from a balcony in New Orleans?

The distinguishing feature of a gallerie in New Orleans is that it is supported by pillars. This architectural element is significant because galleries are typically characterized by their open design, often found on the upper floors of a building and featuring a row of columns. This structure allows for a shaded space that enhances both the aesthetic appeal and functionality, making it a popular feature in the local architectural style.

In contrast, balconies do not necessarily have to be supported by pillars and can be cantilevered, projecting from the building without the same level of support beneath. This difference in support structure is significant in identifying each feature within the context of New Orleans’ rich architectural landscape.
