To soak in the essence of Cartagena, plan to take a stroll down its Calle Mayor, or Main Street. The pedestrian-only avenue is the place to go to appreciate the city’s architecture, go shopping, or even to sit at a restaurant’s outdoor terrace as you watch the world go by.
Just steps away from the port and sea, the street begins at the grand, palm tree-lined Plaza de Ayuntamiento, or Town Hall Square, home to none other than the giant palace that is Town Hall itself. From there, travel past (or stop at) the Roman Theater Museum and onto Calle Mayor with its marble-tiled promenade. Along the way, you’ll walk by noteworthy architecture such as Art Nouveau masterpieces Casino de Cartagena, a fancy 19th-century social club, and Cervantes House (not to be confused by the famous author; this building was named after a wealthy businessman).
