MAAT - A Fábrica da Eletricidade

Once Lisbon's main power plant, this massive riverside building now doubles as both a science and industrial archaeology museum and part of the contemporary MAAT arts complex. The original turbines, boilers, and generators are still standing exactly where they were left, so you get a genuine sense of the scale and grit of early 20th-century industrial life. It's a surprisingly rare combo — raw industrial history sitting right alongside cutting-edge art and architecture.
