Reconstruction of the Heidentor

3D Model

Located in the south of the Roman town of Carnuntum, the Heidentor is the only Roman building that has been preserved above ground. The Heidentor was a cube-shaped building with a side length and a height of around 14.5 m. The core of the four pillars consisted of Roman cast mortar and rubble; the outer shell was made of large stones and brick masonry. For the construction of the Heidentor, older building materials that were already available from other sites (“spolia”) were used. The reuse of stone and brick material was quite common in ancient times. The monument was built to be a triumphal arch in honor of an emperor. The Heidentor can probably be dated in the reign of Emperor Constantius II (351-361 AD).
