Ostia Antica: History and Nature

Ostia Antica can be considered from several angles when planning a trip: the oldest remains known to date point to a fortified castrum, and later Ostia became the capital Rome’s most important trading center as a river port. There is also the Mediterranean nature around the Parco archeologico di Ostia Antica and the birdlife of the Centro Habitat Mediterraneo di Ostia. These themes offer different points of connection as you weigh whether Ostia Antica suits your travel interests.

The early remains of a fortified castrum

The oldest remains of Ostia known to date are the ruins of a fortified castrum from the second half of the 4th century BC. Roman colonists built it to defend the mouth of the Tiber and the coast of Lazio. A castrum is a fortified structure; in Ostia, this type of construction and the stated defensive purpose go together. For travelers interested in history, this makes the early period tangible: it is not just about a date, but also about the purpose the castrum was meant to serve. The reference to the second half of the 4th century BC places the remains within a clearly defined historical period.

Ostia as a river port and trading center

In the 2nd century BC, Ostia became the capital Rome’s most important trading center as a river port. This later role adds an economic focus to the early history of the castrum. The two periods are easy to distinguish chronologically: the ruins of the fortified castrum date to the second half of the 4th century BC, while its importance as a trading center dates to the 2nd century BC. This allows two distinct functions of Ostia to be compared, rather than reducing the place to a single historical role. Those interested in Roman history can take Ostia’s military and commercial significance into account when planning their trip.

Archaeology, Mediterranean nature, and birdlife

The Parco archeologico di Ostia Antica is surrounded by lush Mediterranean nature. So when choosing a destination, the character of the landscape can play a role alongside its archaeological history. Travelers who include nature in their considerations can view this aspect independently of the early fortifications and the later trading role. Another connection to nature is the Centro Habitat Mediterraneo di Ostia: more than 200 bird species have already been recorded there. The number of recorded species may change. The landscape around the archaeological park and the birdlife of the habitat center thus offer different points of connection for travelers who are interested in nature.
