Petrovaradin Fortress: everything to see (and skip)
Sixteen kilometres of underground tunnels, an upside-down clock and the best sunset view in Serbia. Here's what's worth your time.
Petrovaradin — the "Gibraltar of the Danube" — is the reason a lot of people come to Novi Sad. The fortress was built by the Habsburgs between 1692 and 1780 and never taken in a siege. Today it functions as a museum, an artist colony, a restaurant terrace and, one weekend a year, a music festival for 200,000 people.
**Do**: walk the ramparts of the upper town, find the famous reversed clock (the long hand shows hours, the short one minutes — a signal for boatmen on the Danube below), grab a coffee on the terrace with the postcard view of Novi Sad, and if you have time, visit the City Museum in the old barracks.
**Consider**: the underground tunnel tour, which shows off a fraction of the 16 km of galleries under the fortress. It's 40 minutes, cheap, and cool in summer. Book at the ticket office at the top.
**Skip**: the planetarium unless you have kids in tow, and the fortress restaurants at lunchtime — they're fine, but the terrace bars are what you came for. Better to have coffee on the top and a proper meal back in the old town.
**Best time**: golden hour. Sunset paints the fortress walls orange and gives you the best photo of the city across the river. Arrive an hour before, stay for another hour after.
