Pan di Zucchero in Masua (Iglesias) is the tallest sea stack in the Mediterranean: 133 metres of Cambrian limestone rising from the sea off the Iglesiente coast, southwestern Sardinia. A protected Natural Monument, it can be explored by boat from Masua harbour. Nearby: the spectacular 19th-century Laveria Lamarmora industrial archaeology site, perched on the cliffs above.
