The Torre dei Conti was one of the most impressive towers that dominated medieval Rome. It was built in 1238 by Richard Conti, brother of Pope Innocent III as a fortified residence for his family, the Conti di Segni. The tower stood on the border of the territory of the rival family of the Frangipani. Currently standing at 29 metres, it was once 50–60 m tall, and gained the nickname of Torre Maggiore (Major Tower) for its size. Originally covered in travertine salvaged from the ruins of the Imperial Fora, this covering was in turn stripped for use in the construction of the Porta Pia in the 16th century, designed by Michelangelo.
The upper floors were destroyed by a series of earthquakes culminating in the earthquake of 1348, after which it was abandoned until 1620, when it was rebuilt by the Papal Chamber. Other earthquakes in 1630 and 1644 caused damage which was repaired at the end of the 17th century by Pope Alexander VIII, who added two buttresses.
With the opening of the Via Cavour in the 19th century and the Via dei Fori Imperiali in the early 20th century, the tower was left isolated from other buildings. In 1937, the tower was donated by Benito Mussolini to the Arditi (Italian stormtroopers), which retained ownership until 1943. The tower contains the mausoleum of General Alessandro Parisi, whose remains are preserved in an ancient Roman sarcophagus. Parisi, who died in an automobile accident in 1938, was the leader of the Arditi.

The castle is said to have been built by Máel Coluim III of Scotland, after he had razed to the ground the castle in which Macbeth of Scotland according to much later tradition, murdered Máel Coluim"s father Donnchad I of Scotland, and which stood on a hill around 1 km to the north-east.
The first Inverness Castle was partially destroyed by King Robert I of Scotland and a replacement castle was sacked in the 15th century by the Clan Donald during the Siege of Inverness (1429). The castle was occupied during the Raid on Ross in 1491.
In 1548 another castle with tower was completed by George Gordon, 4th Earl of Huntly (1514–1562). He was constable of the castle until 1562.
