Álvaro Siza’s latest project in Portugal is a 16-meter high watchtower built with a lightweight steel structure featuring photovoltaic panels on the roof. This project is very different from most of Siza’s works, both in terms of scale and materials. The watchtower is located in Serra das Talhadas, in the municipality of Proença-a-Nova, and is part of a larger project comprising several structures dedicated to ecotourism in the area, including the Miradouro do Zebro.
