Inside the multi-level brick complex of Trajan's Markets (113 AD) — six storeys of 150 small rooms that served as shops, offices, and administrative spaces. The museum interior tells the story of all five Imperial Fora using fragments, models, and clear English signage. Excellent rooftop views over the entire ancient forum complex.
