Elektrotechnikai Múzeuma (Hungarian Museum of Electrical Engineering)

This museum is unique in that it specializes in just one area and that is electricity. The wide range of historical devices on display is actually rather fascinating (especially the old lamps). The museum traces the history of electricity by examining its generation, distribution and most interestingly, its consumption. There are a variety of weird and wonderful devices, which go into action once a switch is flicked. Admission is free.
