This small beekeeping museum, owned by a family called Zivanovic, feature tools and objects used for keeping bees and producing honey, including some impressive looking beehives, as well as photos and records of the history of this cottage industry in this area. Otherwise, there is nothing really special or much to see. In the same compound is the family's small wine cave, which has produced a few wines that have won awards. My husband expressed interest to the son of the owner who was giving the tour of the possibility of exporting wines (also in the hope of helping in a tiny way, for the outside world to realise that Serbia has many good things about it that's worth knowing about -- by this time, both of us had already felt strongly about spreading this impression in order to dispel the negative views about the country), but he was rather brusquely told that no, they don't produce a lot, and they're only interested in the local market. A dampener, for sure, on our well-intentioned suggestion. In any case, we bought a couple of them, a Merlot and a Riesling, to take back home. As they didn't turn out to be anything particularly notable, we felt somehow vindicated.
