Final answer:
The Insula of Diana, also called the House of Diana, is an example of a multi-story Roman apartment building from the late 2nd century CE, located in the ancient port city of Ostia Antica, Italy.
Step-by-step explanation:
The Insula of Diana is a prime example of Roman architecture from ancient times. Known also as the House of Diana, this building is located in Ostia Antica, Italy, which served as the port city of ancient Rome. The insulae were multi-story apartment buildings where the less wealthy citizens of Rome lived, and the House of Diana stands as a significant example from the late 2nd century CE.
Other illustrious structures from this period include the Colosseum—known for its advanced architecture and the ability to hold large events—and the Pantheon, with its notable coffered concrete dome. Ostia itself was an urban center that boasted a forum, similar to those found in other Roman cities, serving as the focal point for civic, religious, and economic activities, surrounded by temples, markets, and grand public buildings.
