Gorizia Karst
Tour in the unspoilt Karst via Doberdò, home to one of the few examples in Europe of a Karst lake (its water level varies in relation to the flow rates of the Vipacco and Isonzo rivers) and San Martino del Carso, a tiny hamlet in the municipality of Sagrado, completely destroyed in the First World War, known to all thanks to the verses of the poet Giuseppe Ungaretti.
