Quatro Fábricas de Luz

OpenLast checked September 27, 2026

A short industrial-history walk above Lagoa, following the four power stations that lit the island from the 1900s on. From the scout park at Lagos it passes the reservoir that fed the Fábrica da Cidade of 1904 and now feeds the Ribeira da Praia mini-hydro, then the factory ruins themselves. Easy, 2.1 km, an hour and a half.
