Pogonik Castle was built in the early 16th century, probably after the destructive earthquake in 1511. Johann Weikhard von Valvasor wrote that the castle was built from the ruins of the castle at Vernek. A wooden railroad bridge was built across the Sava River at Pogonik in 1848, and the Poganek railroad tunnel was built in 1849. It is long. The wooden bridge was replaced by an iron bridge in 1898. During the Second World War, the Partisans burned Pogonik Castle in 1944 and damaged the railroad bridge.
