Farmlands dominated the neighbourhood until the 1960s and the 1970s. Housing boomed in the western and the eastern sections. It was the city's southeasternmost urban limit until that time when it extended southeastward in the 1970s. Farm production at the time consisted of olive, citrus, cattle and rarely other crops. Residential homes were added between the 1960s to the north and the 1970s to the east. The population slightly boomed until the 1990s when the neighbourhood ran out of space. Until 1995, Akrotiriou had traffic volumes high when the GR-33 moved 3 km south by the Glafkos river.
