Collatia

Collatia was an ancient town of central Italy, c. 15 km northeast of Rome by the Via Collatina.

[1] It appears in the legendary history of Rome as captured by King Tarquinius Priscus.

[2][3] According to Livy, it was taken, along with its population and surrounding land, from the Sabines by Tarquinius Priscus at the conclusion of his war against them.

[4] The date of Tarquinius' triumph over the Sabines, according to the Fasti Triumphales, which Livy says occurred shortly after the surrender of Collatia, is 13 September, 585 BC.

[5] The site is undoubtedly to be sought on the hill now occupied by the large medieval fortified farmhouse of Castello di Lunghezza immediately to the south of the Anio, which occupies the site of the citadel joined by a narrow neck to the tableland to the southeast on which the city stood: this is protected by wide valleys on each side, and is isolated at the southeast end by a deep narrow valley enlarged by cutting.
