What is an exedra typically used for in Roman architecture?

An exedra in Roman architecture is typically designed as an architectural element that provides a space for seating, often arranged around a semi-circular or rectangular area. This configuration allows for a seat of honor, which can serve as a location for an important figure or to display a statue. The design emphasizes social gathering and provides an area where discussions or activities can occur in a comfortable setting. Exedrae are commonly found in public spaces, such as forums and gardens, demonstrating their role in fostering community interaction and civic life in ancient Rome.

The other options focus on architectural functions that do not accurately describe the primary purpose of an exedra, such as housing baths, serving as marketplaces, or providing storage space, which are associated with different types of Roman structures and do not align with the essential characteristics and uses of an exedra.
