Good to know before you go

A square that changed name with the history of Europe

Under the Habsburgs it was simply called Piazza Grande. It took its current name on 3 November 1918, when Italian troops landed right at Molo Audace after Trieste was annexed to the Kingdom of Italy at the end of World War I — an episode the square still carries in its name.

The square is free and always open, but excursions to Miramare Castle and boat trips around the gulf have limited spots: booking ahead is recommended on summer weekends.
