Say a prayer, bow your head and perhaps even light a candle in Cattedrale Santa Chiara. This splendid place of worship may not always be open, so check ahead for hours if you'd like to see inside.
This principal church is one of the best free attractions in Iglesias Historic Centre. If you're eager to explore beyond Cattedrale Santa Chiara, also swing by Masua Mine, Laveria Lamarmora Mine and Church of Our Lady Buon Cammino.
