Cartagena, Spain: Two Thousand Years of Harbor History

The Roman Theatre of Cartagena was excavated beneath the old city center and opened as a museum in 2008. The site is exceptional: a near-complete ancient theater uncovered layer by layer from centuries of medieval construction built directly on top of it. The attached museum traces the excavation and the city's Carthaginian, Roman, and Byzantine periods. Plan ninety minutes here; it earns it.

The city's naval museum, the Museo Naval, documents Cartagena's long history as Spain's principal Mediterranean naval base. It's small but well-curated. The submarine Peral — the first functional electric-powered submarine, built here in 1888 — sits outside in the main square and is genuinely interesting if you notice it.

Calle Mayor is the main pedestrian artery running from the harbor through the old town. It passes modernist townhouses from the early twentieth century, a handful of good tapas bars, and several viewpoints over the port. The walk from the dock to the Roman Theatre takes about fifteen minutes on foot.

The covered market, Mercado Municipal, is on the western edge of the old town and worth a stop before noon. Fresh produce, cured meats, and a few local vendors selling merluza and dorada at reasonable prices. The harbor-front fish restaurants directly across from the cruise terminal are the more convenient option if you want to eat near the ship.

The hilltop castle, Castillo de la Concepción, gives the best view over the port and the surrounding bays. The climb takes about twenty minutes from the harbor. A small elevator runs partway up from the city center. The panorama is worth it on a clear morning.
