The aim of this paper is to determine the possible origin of the stone used for the construction in five cultural heritage buildings
dating from the different historical epochs in Lumbarda, on the island of Korčula, Croatia. Micropetrographic determination of
limestone samples taken from the Roman Villae Rusticae, the old apse of St Križ Church, the Venetian Tower, the Bishop’s Summer
House and St Barbara Church, was done. For comparison, micropetrographic analysis on the rock samples taken from two
abandoned quarries near Lumbarda: the Brendana Quarry in Lumbarda and Gornja Špilja Quarry at Sutvara islet, was also made.
After comparison of their petrographic characteristics, it was concluded that the stone for construction of the Roman Villae Rusticae
and St Križ Church was quarried in Brendana Quarry, while for the other three investigated buildings the material was quarried on
Sutvara islet in Gornja Špilja Quarry. Accordingly, petrographic analysis proved to be useful tool for determination of the origin of
stone and useful for restoration purposes.
