Rociu is a commune in Argeş County, in southern central Romania. It is composed of four villages: Gliganu de Jos, Gliganu de Sus, Rociu and Şerbăneşti.
The oldest relicves come from the Bronze Age, from Şerbăneşti Village. Then, much later, the village Gliganu is mentioned, on June 12, 1564. The village belonged to a boyar from Rucăr. According to the same source, all four villages are mentioned after 1830. In the Communist period, the commune received a strong impulse for economic growth: A 25 km long irrigation canal was built to drain water from the Argeş River. Rociu received special attention because there was built a farm of the Communist Party.
Rociu is situated in the southern part of the Argeş county, in the Găvanu-Burdea plains. It is situated 25 to 30 kilometers from Piteşti, the main town of the county. The average altitude is 240 meters.
There are 4 villages: Rociu, Gliganu de Jos, Gliganu de Sus and Şerbăneşti.
The Găvanu-Burdea plain is a flat region, with large and fertile valleys. Rociu is situated close to the Dîmbovnic River (sometimes called Dâmbovnic or Drâmbovnic). There are a few smaller rivers that are dry in summer, like Mozacu River and Gliganu River. There are many small lakes, used for fishing.
