Being enclosed
One of the unique features of Persian gardens
is being fenced or walled around its perimeter.
Introversion has been rooted in Persian beliefs and
culture and it is evident in almost every feature of
Iranian architecture. In this sense, the whole plan
and structure of Persian gardens had been enclosed
within walls to provide the image of an internal
paradise in the heart of deserts guarded against
the eyes of strangers (Fig. 9). The function of these
walls was not only to create a boundary, but also to
act as an interface between the dry hot outer area
and the green, shady and semi-paradise inner area
(Massoudi 2009).
