• Entry is by guided tour, starting on the hour and lasting about 45 minutes, so arrive 15 minutes early
• Cash only, in Serbian dinars, since the museum takes no cards
• Tours in English or Serbian, with no booking needed for families; groups over 10 must book a day ahead

The museum follows Nikola Tesla as an inventor and as a person, through authentic working models of his machines, his personal belongings and a film about his life by Dr. Branimir Jovanović.

Every visit is a guided tour, so a guide walks each group through the rooms and presents the machines. It suits school-age kids curious about electricity and inventions more than toddlers.
