Found lurking inside another of the city’s fine, late 19th-century neo-Renaissance buildings complete with fine painted ceilings and elaborate sculptures on the stairs, this is the oldest museum in country, founded way back in 1821. Permanent displays include an intriguing collection dedicated to the Slovenians and the Slovenian language alongside the usual bits and pieces of interest dug out of the ground, plus a large ensemble of almost 200 examples of carved stonework dating from Roman times excavated in the city and surrounding regions.

Admission €4-8.5.
