The remains of the former Venetian border hidden in the cadastral municipality boundaries on the Kraški rob plateau around Črnotiče

The remains of the former Venetian border have been preserved in some places as boundary points of the cadastral municipalities. On the Kraški rob, Slovenia, special elongated piles of stones have been preserved, which are called muše by the locals. We measured 27 of them on the southern border of the cadastral municipality of Črnotiči. Two natural boundary points from the time of the Venetian Republic were identified: Brstenik spring and a small cave near a doline called V jami. Additionally, three carved limestone boundary stones from the time of the Franciscan land cadastral survey bearing the year 1819 and 21 boundary marks, mostly without inscriptions (two with the year 1865), located on or near the northeast border of the cadastral municipality of Črnotiči, are presented. Here, the Špirnica cave was also identified as a boundary point, at least since the time of the Franciscan land cadastral survey. At Krapnik, named on the Franciscan land cadastral map Rjavi kamen u štirni (Eng. brown stone in the well), a boundary stone of the three cadastral municipalities of Črnotiče, Podgorje, and Podpeč can be found. It is a larger, roughly hewn stone of a dark brown colour, with the year 1865 carved into it and the remains of fan-shaped lines on one side and a decaying circular shape on the other. It is located just 500 m north of the former corner point of the Venetian border on Debeli hrib, so it may even be an old Venetian boundary stone.
