Tarragona holidays

Built over Tarraco, the Roman capital of the province of Hispania Tarraconensis, Tarragona is a port city on the Costa Daurada in Catalonia, about 100 km south-west of Barcelona. Its Roman remains are a UNESCO World Heritage Site, and the amphitheatre stands right above a city beach.

Beaches

Platja del Miracle, the main beach of Tarragona, lies below the amphitheatre, a short walk from the old town, with fine sand and a long promenade. To the north, L'Arrabassada is a smaller bay popular with families, and Platja Llarga, around 3 km long, backs onto pine woods. Beyond it, paths lead to quieter coves such as Cala Fonda, and further north Altafulla and Torredembarra have sandy beaches and small old towns, a few minutes away by train. The sea temperature on this page is measured off Platja del Miracle.

Things to do

The amphitheatre, where gladiator fights were held, looks straight out to sea from the Balcó del Mediterrani viewpoint. Parts of the Roman circus survive in vaults under the old town, and the walk along the Roman walls leads up to the cathedral. West of the Rambla Nova, the Colonial Forum keeps columns of the Roman city's main square. About 4 km north of the centre stands the Les Ferreres aqueduct, known locally as the Pont del Diable. Tarragona is a stronghold of castells, the Catalan human towers, which are built at the Santa Tecla festival in September. PortAventura World lies about 10 km along the coast. By the fishing port, the Serrallo quarter has seafood restaurants and a fish market.
