Bohonal, in the north-east of the province of Cáceres, is home to the ruins of the ancient Roman city of Augustóbriga, buried below the town of Talavera la Vieja. The area was flooded by water when the Valdecañas reservoir was built in 1960.
The ruins of Augustóbriga include the temple and other historical references of what the city was like thanks to documents from Cornide and Hermosilla in the 18th century and, later, Mélida.
We know that walls protected and surrounded the city in Roman times. The centre was where the forum was located, surrounded by administrative and religious buildings.
The most prominent of the ruins are those of the temple known as ‘Los Mármoles’, dating from the 2nd century, which was dismantled stone by stone in order to rebuild it on an inlet above the maximum level of the reservoir water, 6.5 kilometres from the ancient settlement. Four front and two side columns form its portico or main façade on which the architrave, and, above it, there is a small rounded arch. The building is made of granite.
Together with the temple, there were also three column fragments from the so-called Temple of La Cilla.
The city had an aqueduct that was one metre tall, as well as a system of underground channels that distributed water from a reservoir. There are also remains of thermal baths and roads, the latter of which can be found near Alija Castle.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
