The Mausoleum of Augustus is a large tomb built by the Roman Emperor Augustus in 28 BC. The interior of the mausoleum is not open to tourists. The mausoleum was one of the first projects initiated by Augustus in the City of Rome following his victory at the Battle of Actium in 31 BC. The mausoleum was circular in plan, consisting of several concentric rings of earth and brick, planted with cypresses on top of the building and capped by a conical roof and a statue of Augustus. Vaults held up the roof and opened up the burial spaces below.
In the Middle Ages the tumulus was fortified as a castle and occupied by the Colonna family. After the disastrous defeat of the Commune of Rome at the hands of the Count of Tusculum in 1167, the Colonna were disgraced and banished, and their fortification in the Campo was dismantled. Thus it became a ruin.
It was not until the 1930s that the site was opened as a preserved archaeological landmark along with the newly moved and reconstructed Ara Pacis nearby. The restoration of the Mausoleum of Augustus to a place of prominence featured in Benito Mussolini's ambitious reordering of the city of Rome which strove to connect the aspirations of Italian Fascism with the former glories of the Roman Empire.

The keep dates from the Christian era. It has a square base and small dimensions and is located at the highest part of the crag.
There are some other enclosures within the tower that create a small alcázar which is difficult to access.
In a lower area of the castle, protected with defensive remains of rammed earth and irregular masonry, is an old Muslim farmstead.
After a recent restoration, an open-air theater has been built on La Iruela castle enclosure. This theater is a tribute to the Greek and Classic Eras and holds various artistic and cultural shows throughout the year.
The first traces of human activity in La Iruela area are dated from the Copper Age. An intense occupation continued until the Bronze Age.
Originally, La Iruela (like Cazorla) was a modest farmstead. From the 11th century, a wall and a small fortress were built on the hill to protect the farmers.
Around 1231, don Rodrigo Ximénez de Rada, Archbishop of Toledo, conquered La Iruela and made it part of the Adelantamiento de Cazorla. Over the Muslim fortress, the current fortress was built.
Once the military use of the fortress ended, it was used as cemetery.
