Lisbon Metro has opened three central stations overnight to provide emergency shelter for people experiencing homelessness amid cold weather. Oriente (Red Line), Rossio (Green Line) and Santa Apolónia (Blue Line) will be accessible from Friday through the early hours of Tuesday at least, a period that the city warns may be extended or shortened depending on ongoing weather assessments. The move — driven by concern from Lisbon City Council — uses transport infrastructure as temporary refuge and highlights the need for coordinated short-term protection and wider services for people sleeping rough during extreme conditions.
