We conducted dendrochronological investigations of oak (Quercus sp.) from the hill Rožnik in Ljubljana, central Slovenia. Using the TSAP-Win we performed measurements and constructed a local chronology, based on samples taken from 20 fallen oak trees. The samples (discs) were collected from fallen trees after a disastrous ice storm in 2014. The chronology is 184 years long and extends from 1830 to 2013. The chronology was compared with other oak chronologies from different sites in Slovenia, Austria, Hungary, Croatia and Serbia. Teleconnection survey showed that the chronology of Rožnik statistically agrees (TVBP>4) with two oak chronologies of Slovenia (the ones from Ljubljana 305 m a.s.l., and Novo mesto 188 a.s.l., distance 61 km), and two chronologies from Austria (Klagenfurt 462 m a.s.l., distance 65 km, and Fechring 309 m a.s.l., distance 154 km). The chronology of Rožnik was also compared with beech (Fagus sylvatica L.) chronologies from different sites in Slovenia. The heteroconnection research has shown that it statistically agrees (TVBP>4) with three chronologies of beech from different localities in Slovenia (Mokronog. 400 m a.s.l., distance 39 km; Mašun 1000 m a.s.l., distance 36 km; Celje 300 m a.s.l., distance 60 km).
