Where to find it, when to visit, how much does it cost?
National Museum of Romanian Police is located on Calea Domneasca at number 185 in Târgoviște, Dâmbovița county. You can park in front of the Chindia stadium, on the right, on the street perpendicular to Calea Domneasca, before the museums area, as you come from Bucharest. Coming on foot, we walked past the former Tribunal, today the History Museum, at number 189, and entered the next courtyard, where the former Prefecture, today the Art Museum, is. Somewhere at the back of the courtyard is the museum I'm telling you about; it's a white, one-story building.
The entrance fee is 5 lei / person. The tour is guided by a competent and pleasant guide. The museum is open Tuesday through Sunday from 9 to 17.
