One of the important functions of every Semiotic system is its local function. In a discourse, places have various roles such as objective, acting, being, abstract, narrative and mythical. In addition they have referential, narrative, tensional, metaphorical and transcendental functions and they play a role in creation of meaning. By strengthening objective and physical aspects of place, its cognitive dimension gets strong, while by making these aspects weaker its metaphorical dimensions are strengthened. Therefore, place is transformed into space disruption. In the "The Night when Sohrab was killed", place transforms in a way in relation to acting discourse, reciprocity and their interaction; Place becomes flexible and acquires a trans-place characteristic. The main question of the research is how and by what process does transformation of place happen, and what function leads to this transformation. The current research is on the basis of the hypothesis that place in accordance with its functions of reciprocity, interaction, and interactive action-oriented features acquires an identity and static function. The effect of such functions on place is that it leads to its flexibility in the realm of place and space and eventually it becomes an existential and transformational place, which its main output, on the one hand, is interaction of the actor and place and on the other hand, its unity and harmony with Sohrab's mythical features and universe. The purpose of this research is to study Semiotic characteristics of place and space and to analyze conditions, place transformation and conversion of place into trans-place. This research showed that different continuous locations, non-continuations, induction, whirlwinds, and transcendence play a role in this discourse, and so these places always have active, static, emotional, inductive, mythical and transcendental functions.
