A cute compact museum. There is information in Russian. The visit took about 40 minutes. A great option if you get caught in the rain while walking around the old town)
The Archaeological Museum of Budva, exhibits finds from the excavations of the Greek and Roman necropolis.
Most vacationers will just be bored here. People who are in the subject can visit, but the exposition is tiny, there are few really interesting artifacts.
There is a perfectly preserved Greco-Illyrian helmet of the 5th century BC, objects made of glass, gold jewelry and ceramic dishes.
The museum is difficult to find, it is located in the farthest part of the Old Town.
