The architectural space concept is closely united with the fundamental space concept which lies at the root of human existence. So the definition of the architectural space concept is deeply depended on analysis of the fundamental space concept. The purpose of this paper is to present an introductive study of this fundamental space concept. In this part, I investigate about fundamental spatiality which has been already comprised in the phaenomenon of "Weltbild"-the conception of World. The world, as the unity of meanings, is organized and consisted of the cognition that is already estabrished. The cognition is estabrished by putting particuler experiences into spatial and temporal order. This demand (Das postulat) of spatial orientation is the spatiality as the epistemological foundation. In other hand, the concept of "world"-"Weltbild" is the "understood" world and it is changed by the substance of comprehension. This substance is the way of "understanding", and it is determined on historical situation (social and cnltural). This way of "understanding" is the foundation of "understanding world". It provides vacant epistemological foundation with concrete substance, and embodies the "Weltbild". The above is investigated on "Gestalt-Change" of "weltbild" which had happened bitween the Mediaeval and the Modern.
