Which king is known for building significant infrastructure in ancient Rome?

Tarquinius Priscus is recognized for his pivotal role in early Roman infrastructure development. He is credited with initiating major construction projects that laid the groundwork for the city's urban landscape. Under his reign, he oversaw the building of the Circus Maximus, an essential venue for public games and chariot races. Additionally, he contributed to the construction of temples and the development of drainage systems, which were crucial for managing the urban environment and public health.

While other leaders such as Julius Caesar and Augustus also made significant contributions to infrastructure, their efforts came during a later period in Rome's history when the city had already been established. Numa Pompilius is known for his religious contributions rather than infrastructure projects. Tarquinius Priscus’s efforts were critical in shaping early Roman society and set important precedents for later developments in the city.
