Zakladna najdba z Grdavovega hriba pri Radomljah

Arheološki Vestnik, 2015
V poznoantični naselbini Grdavov hrib pri Radomljah je bil leta 1996 odkrit depo sočasnega orodja, nedvomno namenjenega obdelavi lesa. S sondiranjem in preverjanjem natančne lokacije so bile odkrite še druge naselbinske najdbe.
