Muzeum Gazownictwa w Paczkowie

A former gasworks from the early 20th century that still has its entire town-gas production line intact. Visitors walk through the buildings and plant, and the grounds are lit by working gas street lamps. The 3,000-plus exhibits include stoves, heaters, irons, curling tongs and even a gas refrigerator, most still in working order. Worth seeing is the collection of 600 household gas meters, the largest in Europe in one place.
