Location

The Roman Bridge of Segura stands over the Erges River, marking the natural border between Portugal and Spain. It is located in the town of Segura, belonging to the municipality of Idanha-a-Nova, in the interior of Portugal's Central region. Its position allows for the crossing of a river valley, integrating imposingly into the surrounding landscape and remaining a link between the two countries.

A Work of Antiquity

This remarkable structure dates back to the 2nd century AD, having been erected during the reign of Emperor Trajan. It was conceived as an integral part of an important Roman road, essential for connecting ancient cities like Mérida, in present-day Spain, and Egitânia, which corresponds to present-day Idanha-a-Velha in Portugal. Its construction at that time underscores the strategic importance of the region within the vast Roman road network.

Architectural Features

The bridge is an impressive manifestation of Roman engineering, characterized by its five stone arches that span the Erges River. Originally built with granite blocks, some of large dimensions, its robust design allowed it to withstand the passage of centuries. Throughout its long history, the bridge has undergone restoration interventions, notably in the 16th century, by Portuguese stonemasons. These works were carried out with such skill that the reconstructed arches blend remarkably with the original section, respecting the bridge's typology. More recently, it has been subjected to interventions that, while ensuring its continuous functionality, have modified some aspects of its older design.

Significance and Persistence

The Roman Bridge of Segura holds considerable historical and architectural value. It is one of the rare large-scale Roman bridges that survive in Portuguese territory and which, despite successive interventions, has largely preserved its original essence over the centuries. Its continuous functionality, crossing borders and generations, is a lasting testament to the durability and constructive intelligence of the Romans, and the resilience of built heritage.
