Col, Ajdovščina
Name
The settlement was first attested in written sources as Zoll oder Podgweld and Zoll oder Podgwelb in 1763–1787. The Slovene name Col is borrowed from Middle High German zol (modern German Zoll) 'toll' or 'customs duty'. Col is located on the border between the historical Habsburg crown lands of Carniola and Gorizia and was a collection point for tolls. Col was originally known as Podvelb (German: Podgwelb; literally, 'below the arch') in reference to a castle that formerly stood near Saint Leonard's Church.
Trilek Castle
Trilek Castle stands west of the center of Col. It was used for defensive purposes against Ottoman attacks, and it was owned by the Abramsberg noble family, resident in Šturje. The castle is now in ruins dating from the 16th century, and only the tower is preserved. Archaeological finds at Trilek Castle include a Roman milestone that was found in the 19th century; it bears a dedication to Julian the Apostate and is held by the National Museum of Slovenia. Roman coins dating from the second century AD have also been found at the castle.
Church
The parish church in the settlement is dedicated to Saint Leonard and belongs to the Diocese of Koper.
