Crack monitoring in the Baptistery of the Euphrasian Basilica in Poreč

In this paper we present six-month results of an ongoing structural monitoring of the Baptistery in the Episcopal Complex of the Euphrasian Basilica in the historic centre of Poreč, which is under UNESCO’s protection as one of the best preserved complexes of early Christian architecture in the world. The complex is located by the sea and is partially still being used for its original function. Two wide and more than five meters long vertical cracks have been present for some time in the Baptistery, so the authorities decided to undertake a continuous crack width measurement. Automatic static monitoring system was installed with the aim to determine (i) if the cracks are active and (ii) if there is a correlation between the crack opening and the environmental parameters or the sea level oscillations. Such a continuous structural monitoring is a good way of getting necessary data in order to properly assess and extend the life time of heritage structures.
