One day is really short—I think you can reorganize things a bit to be more efficient. With the current order, you’ll just walk past St. Mark’s Church without seeing it, and then take a detour to come back to Gradec to see it.
Are you staying overnight? Or are you leaving at the end of the day for Slovenia?
For parking, I’m not sure if you’re talking about the garage at Langov Trg—it’s probably the most reliable spot to find parking easily. The cathedral has been under reconstruction since the 2020 earthquake; when I passed by two years ago, all you could see was scaffolding. Too bad, because the façade is normally really impressive. For the itinerary, I’d suggest:
- Dolac Market
- Stone Gate (Kamenita Vrata)
- St. Mark’s Church (which, incidentally, was also under reconstruction in 2023)
- Head down Sv. Cirila i Metoda Street toward the tower. The façade of the Greek Catholic Church is worth a quick look. You won’t have time, but just nearby, the Croatian Museum of Naïve Art is really great, even for kids.
- Lotrščak Tower and St. Catherine’s Church
- Grič Tunnel if you really want to. The issue is that the tunnel runs east-west under the Upper Town, but you’re heading south. Given the limited time, I’d enjoy the view from Strossmayer Promenade instead and take the funicular down to the Austrian part of the city (one of the best views in town is right next to the funicular).
- Then...
The most beautiful buildings in the Lower Town are arranged in a horseshoe shape. To the northwest is the city’s most stunning building (the National Theatre—Hrvatsko narodno kazalište). From there, you can head south to the imposing National Archives building (Hrvatski državni arhiv) and its owls. Then, it’s east toward the Esplanade Hotel and the train station. (Just a little north of the Esplanade, there’s a Manneken Pis peeing into the pond in Petra Svačića Park.) Finally, head back north via the Art Pavilion, Zrinjevac Park, and Ban Jelačić Square. If you can stay for dinner, there are plenty of terraces and lively spots on Tkalčićeva Street, though it’s not as charming as the riverside in Ljubljana.
