Museums, due to constantly changing socio-political needs, are evolving and are becoming more and more transformed from educational centers to multi-dimensional experience spaces. This research attempts to study the way in which architecture affects the museum experience. We will argue that the spatial properties of a building can be used to highlight the exhibits and build the desired experience. In addition, we will attempt to show how architecture affects museum experience through the way the building orga-nizes the space, permits or hinders movements and views, and builds a set of relationships between the exhibition spaces, the exhibits and the visitors. If we take a look at the architectural bibliography, we will see that emphasis is placed mainly on the visual form and the shell of buildings, and not so much on their spatial issues or the results they bring to visitors. Thus, based mainly on museum bibliography, which suggests theories on the experience of the visit, we will try to investigate whether the role of space in an exhibi-tion can extend beyond the representation of knowledge organization and contribute to the creation of independent results.

The museum experience is always in relation to the social factor, the walking process and the views inside it, which will be analyzed showing that each museum uses them differently according to the overall experience it wants to give the visitor.

In conclusion, in order to further understand the above, two different museum cases, that of Tate Modern in London, and the Museum of Byzantine Culture in Thessaloniki will be examined and compared.
