Porta Maggiore is an ancient stone gate constructed in AD 52 during the reign of Emperor Claudius. Its design is remarkable because it was formed by the intersecting arches of two Roman aqueducts, creating a grand and functional city entrance. Over time, this impressive structure became part of the larger protective Aurelian walls that surrounded Rome, serving both as a gateway and a part of the city’s defenses.
Not far from Porta Maggiore stands the well-known “Baker’s Tomb.” This unique monument was built by a former slave who, after gaining freedom, became a successful baker. He erected the tomb for himself and his wife, celebrating both their lives and achievements. Visitors will notice decorative friezes along the top of the tomb, each one carefully carved to show different stages of breadmaking. These detailed scenes offer a glimpse into daily life in ancient Rome and highlight the importance of bread in the city’s culture.
