On its opening day in 1902, more than 3,000 Lisboetas bought tickets to ride the Santa Justa Lift, despite a freak storm of torrential rain and lightning. Their enthusiasm was understandable, Raoul Mesnier du Ponsard, a Porto-born engineer who had studied under Gustave Eiffel, had solved one of the city's oldest problems with 45 metres of neo-Gothic ironwork.

The lift connects the flat streets of the Baixa to the Largo do Carmo, a climb that had defeated various proposals since the 1870s, including one involving animals hauling carriages up rails. Originally steam-powered, it carried half a million passengers in its first year alone and was classified as a National Monument in 2002.

VoiceMap's self-guided audio tours trace the lift's place within the Baixa Pombalina, connecting its iron lattice to the broader story of Lisbon's post-earthquake reconstruction and explaining how Eiffel's techniques ended up scaling a Portuguese hillside.
