6) Noon. Off the menu

It doesn’t get any more local than Konoba Fiume. On an alley next to the market, this is the sort of diner where, under vaulted ceilings, fishermen sit with lawyers, and dock workers share tables with politicians. Though Fiume serves scores of tempting, moderately priced dishes like homemade pasta with shrimp and truffles (90 kuna), consult the chalk board’s fresh offerings, close the menu and say one word: “brudet”: a mixed-fish stew made with the day’s best seafood (50 kuna). Surrender to the restaurant’s ingredient suggestions, but ask nicely, and for about 90 kuna more, add the succulent scampi.

7) 2 p.m. History, art and tech-nostalgia

Dive deeper into this eclectic port at the Maritime and History Museum of the Croatian Littoral (admission, 20 kuna), in the neo-Renaissance Governor’s Palace, built in 1897. The exhibitions cast a wide net: Bronze Age findings, an interactive city model, ancient ships’ logs and a life vest from the Titanic. The Peek & Poke Computer Museum (30 kuna) packs in more than 7,000 mint-condition, tech-nostalgic items. The evolution of calculators, computers, phones, TVs and video games from every era fill each pixel of space. Finally, the Museum of Modern and Contemporary Art was relocated in 2017 to a complex that once included a sugar refinery and tobacco factory. The venue’s 6,500 square feet house some 8,000 pieces; exhibitions of photography, paintings, sculptures, drawings and film rotate bimonthly (10 kuna).
