Casalotti is the name of the forty-eighth zone of Rome in the Agro Romano, denoted by Z. XLVIII. It is the namesake of the frazione of the same name. The area takes its name from the main road to Casalotti name, probably due to the numerous houses that were in the area. Surrounded by green hills, the center of the hamlet of Casalotti (Ormea Square and Church of St. Rita of Cascia) is situated at an altitude of about 110 m above sea level.

It is located in the north-west of Rome, outside the Ring Road. The area borders:

• north-west zone Z. XLIX Santa Maria di Galeria
• area to the north by Z. LI The Retort
• north-east area Z.L Octavia
• west suburbs with the Triumphal SX IX and S. Aurelius
• south-west zone Z. XLV Castel di Guido

In May 1944, it was destroyed by Allied bombing along with the nearby Grottarossa, during the advance of the Allies themselves to hunt the German settlements.^[1] The real estate boom dates back to the 1970s, when many construction companies started to build the most ancient part (the square and the area from Via Trofarello). Yet it is still being expanded. On 29 September 2009 the president of AS Roma Rosella Sensi announced the project of building a new soccer stadium in the southern area, near the Via Aurelia.
