Abstract This paper discusses the architecture of cities for children. It is based on the hypothesis that present-day city architecture does not properly consider children as equals to adults. The aim is to rethink the whole city architecture by identifying children's architecture, which is a missing complementary part in architectural knowledge and practices. Can a complementary part achieve a city that functions totally for children? The paper traces the historical roots of this issue from the earliest civilizations till the present, explaining the main forces behind this and how they have established the tradition of adult architecture. The results of this paper can provide important guidelines to reform the present city's architecture, which can cover all age groups. The paper uses cases from Norway, the United Arab Emirates, and Saudi Arabia.
