BostonBostonLisbonLisbon
Trafaria Praia is a passenger ferry built in 1960 that used to ply the river Tagus between Lisbon and Cacilhas until it was decommissioned in 2011. Under the direction of Joana Vasconcelos, the ferry underwent a major transformation, which included encasing the exterior of the vessel from stern to prow in a wrap-around frieze of over 7,000 traditional tin-glazed, blue-and-white, hand-painted azulejo tiles depicting 20 kilometers, or 12 miles, of the Lisbon skyline, from the Bugio Tower to the Vasco da Gama Tower. Below the ship's deck, Joana Vasconcelos covered the ceiling and walls with blue and white fabrics and crocheted pieces intertwined with LEDS creating a mysterious, dark-blue sea cave that pulsates with fairy lights and gently vibrates with the ship's engine. It envelops visitors and elicits both an intellectual and a sensorial response. The ship was shown at the 55th Venice Biennale (2013) as the Portuguese pavilion; it currently moors not far from where actual passenger ferries carry commuters across the Tagus. It is open for visits and short river cruises.

Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.

Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
