The Slovenian Iron‑making Museum stretches across Stara Sava, a perfectly preserved 17th‑century ironworks settlement in Jesenice. Walk through the old blast furnace, workers’ cottages and the elegant managers’ residence to trace Slovenia’s journey from charcoal forges to industrial steel. Hands‑on exhibits let you pump bellows, test ore samples and compare the age of bloomeries with today’s high‑tech mills, while the authentic riverside setting—immortalised in Valvasor’s 1689 copper engraving—immerses you in the daily rhythm of hammer and anvil.
