Best Things to do in Cartagena Spain

Explore the impressive Roman Theatre

One of the absolute must-sees in Cartagena is the Roman Theatre, and not just because it’s nearly 2,000 years old. Dating back to the 1st century B.C., this architectural wonder was hidden for centuries beneath buildings in the heart of the city, only rediscovered in 1988 during routine construction work (talk about stumbling onto history!). Today, it’s been beautifully restored and proudly showcases Cartagena’s Roman roots. Right next door, the museum takes you deeper into the past with artifacts unearthed on-site and a clever underground route that leads you straight into the theatre itself.

Walk to the Roman Forum and the thermal baths

Just a short walk from the Roman Theatre, the Roman Forum District offers another captivating glimpse into ancient Carthago Nova. Here, you’ll find the remains of thermal baths once reserved for the Roman elite, along with intricate mosaics that have survived nearly two millennia. It’s like stepping into the daily life of a wealthy Roman household in the 1st century. For an even closer look, don’t miss the Casa de la Fortuna (“House of Fortune”), a remarkably preserved Roman domus tucked away in Cartagena’s old town, complete with wall paintings, tiled floors, and a name that still sparks curiosity.

Visit the Naval Museum & Isaac Peral’s Submarine

Dive into Cartagena’s seafaring soul at the Naval Museum, where Spain’s maritime legacy comes to life ,quite literally, with the original Isaac Peral submarine on display. Designed in the late 19th century by the Cartagena-born engineer himself, this pioneering vessel changed the course of naval history and stands proudly as the museum’s star exhibit. Housed within the city’s historic naval base, the museum is a treasure trove for anyone curious about submarines, military ships, or maritime innovation.

Marvel at Muralla del Mar and the city walls

Running alongside the scenic Paseo de Alfonso XII, the Muralla del Mar, or “Sea Wall”, is one of Cartagena’s most iconic historical landmarks. Built in the 18th century as part of the city’s military defenses, it once protected this vital Mediterranean port from potential invaders. Today, it stands as a proud reminder of Cartagena’s strategic importance and layered past. As you stroll along its length, you’re walking the same route that once guarded a bustling naval hub, with panoramic sea views that make the history lesson all the more enjoyable

Wander the Molinete Hill Archaeological Park

If you’re up for a short climb and a step back in time, Cerro del Molinete is calling your name. Right in the center of Cartagena, this hill has been turned into a fascinating archaeological park where you can roam through the ruins of ancient Carthago Nova. Think Roman temples, streets, houses, and even baths, all once part of a lively neighborhood nearly 2,000 years ago. It’s the kind of place where history isn’t locked behind glass, but right under your feet. Plus, the views from the top? Worth every step.

Climb to Castillo de la Concepción

Perched above the city, Castillo de la Concepción is the place to go when you want Cartagena at your feet, literally. This medieval fortress offers some of the best panoramic views of the city, port, and surrounding hills. Inside, modern exhibitions walk you through Cartagena’s layered past, from Roman times to the present day. But honestly? Even if you just go for the views, it’s worth the climb. It’s the perfect spot to get your bearings, snap a few photos, and imagine how this strategic hill once kept watch over the entire coastline.

Snap a photo at the Port of Cartagena

Right on the edge of the Mediterranean, the Port of Cartagena is where the city’s rich history meets its vibrant present. Once a major hub for ancient trade, today it welcomes cruise ships, yachts, and curious travelers from all over the world.

Come here for a relaxed stroll, stay for the golden-hour glow, and don’t forget your camera, it’s the kind of place where every sunset feels like a postcard.

Capture the Town Hall in Plaza del Ayuntamiento

Standing proudly in the heart of Plaza del Ayuntamiento, Cartagena’s Town Hall (Ayuntamiento) is a showstopper you won’t want to miss. With its gleaming white marble façade and elegant Neoclassical design, this landmark is one of the city’s most photographed buildings, and for good reason.
