The Palacio Consistorial de Cartagena is a historic building located in the city of Cartagena, in the Region of Murcia, Spain. It was built in the late 19th century by architect Tomás Rico Valarino in a neoclassical style, and served as the city hall of Cartagena for many years.

The building features a central tower that rises above the rest of the structure, and is topped with a clock and a cupola. The facade is decorated with ornamental motifs, including Corinthian columns and arches, and the entrance is marked by a large doorway with a semicircular arch.

Inside, the Palacio Consistorial de Cartagena features a number of impressive spaces, including the Salón de Sesiones, which served as the city council chamber, and the Salón de Plenos, which was used for official ceremonies and events. These rooms are richly decorated with frescoes, murals, and sculptures, and contain historic furnishings and artifacts.

Today, the Palacio Consistorial de Cartagena is no longer used as the city hall, but instead serves as a cultural center and museum. Visitors can explore the building and learn about the history and culture of Cartagena and the surrounding region through exhibits and displays. The building also hosts a variety of cultural events, including concerts, exhibitions, and lectures.
