Zgodovinska pot v okviru projekta »Mrouce cajta« (narečno »Drobtinice časa«) nas po Podbrdu vodi skozi čas po prvi svetovni vojni (1918–1947), ko je po obronkih na njegovi severni, vzhodni in južni strani potekala rapalska meja med Kraljevino Srbov, Hrvatov in Slovencev ter Kraljevino Italijo.
Part of the “Mrouce cajta” project (a dialect phrase meaning tiny bits of time), the history trail guides us through the settlement of Podbrdo during the period 1918-1947 after WWI, when the Rapallo border between the Kingdom of Serbs, Croats and Slovenes and the Kingdom of Italy ran along the ridges on its northern, eastern and southern sides.
