Passengers travel upwards on Lisbon's Bica funicular September 1, 2008. Different in shapes but serving one function -- simplifying access to the upper town in the hilly Portuguese capital -- Lisbon's street elevators are national monuments. The motors and most moving parts date back to early 1900s when the machines swapped steam for electricity. But they are more than just functioning museum pieces or charming tourist attractions. City dwellers who work in the upper town still hurry to catch them in the morning to avoid a tiring hike up the cobbled pavement and to save their soles and heels. Picture taken September 1, 2008.
