Dom Luís I Bridge

The Dom Luís I Bridge is a double-deck iron arch bridge linking the Ribeira district of Porto with the Vila Nova de Gaia port-lodge waterfront across the Douro River in northern Portugal. Opened in 1886 and designed by Théophile Seyrig, a partner and former associate of Gustave Eiffel, it carries a metro line and pedestrians on the upper deck about 60 metres above the water, and road traffic and walkers on the lower deck beside the quays. The 172-metre arch is the defining silhouette of the Porto skyline. Walking the upper deck takes about 10 minutes each way and delivers wide views of terracotta roofs, the Sé Cathedral, the Serra do Pilar monastery and the rows of port wine lodges opposite. The lower deck is more sheltered and places walkers close to the river, with views of rabelo boats and the Ribeira waterfront. Visitors can cross at either level, and many walk up on one side, cross, and descend by the Funicular dos Guindais or the Gaia cable car. The best vantage points are the upper-deck platform at the Porto end, the Jardim do Morro in Gaia and the Ribeira quay. Sunset is the most popular time, when the metal and the surrounding granite glow orange and the upper deck fills with photographers. Midday is hot and exposed, and the upper deck has little shade. Mornings are calmer, and after dark the illuminated arch is reflected in the river. The upper deck is an open walkway with railings beside the metro tracks; visitors with a fear of heights may prefer the lower deck. Wind can be strong. Allow 30 to 60 minutes for a crossing with photography stops. The bridge is free and open at all hours, and busy street performers and divers sometimes gather near the Gaia end in summer.
