3D model creation and visualization is often used in digital preservation of looks and structure of historical buildings. Virtual reality (VR) technologies facilitate this 3D model creation and visualization. 3D scanner can be used for acceleration of the data collection and model creation. 3D displays can be used to improve visual perception and 3D printing can be used for physical model creation. In this paper is presented the way for preservation of historical buildings using virtual reality technologies. Example of preservation procedure, which consists from 3D scanning, 3D model creation, optimization and visualization, is shown on the historical building of The State Theatre of Košice.
