is civilization ki sabase vishesh baat thi yahaan ki vikasit nagar nirmaan yojanaa. Harppaa tathaa mohan jodaro dono nagaron ke apane durg the jahaan shaasak varg kaa parivaar rahataa thaa. Pratyek nagar men durg ke baahar ek ek usase nimn star kaa shahar thaa jahaan inton ke makaanon men saamaany log rahate the. In nagar bhavanon ke baare men vishesh baat ye thi ki ye jaal ki tarah vinyast the. Yaani sarke ek dusare ko samakon par kaatati thin aur nagar anek aayataakaar khandon men vibhakt ho jaataa thaa. Ye baat sabhi sindhu bastiyon par laagu hoti thin chaahe ve chhoti hon yaa bari. Harppaa tathaa mohan jodaro ke bhavan bare hote the. Vahaan ke smaarak is baat ke pramaan hae ki vahaan ke shaasak majadur jutaane aur kara-sangrah men param kushal the. Inton ki bari-bari imaarat dekh kar saamaany logon ko bhi yah lagegaa ki ye shaasak kitane prataapi aur pratishthaavaan the.
