In Cartagena, the Casa de Rafael Núñez is a mansion that was once home to the famous politician, poet, and lawyer Rafael Núñez. The country's president on four occasions, Núñez' importance in Colombian history cannot be overstated — not only did he write the country's 1886 constitution, in effect until 1991; he also wrote the words to the Colombian national anthem.
A three-minute walk from the Walled City in El Cabrero, the Caribbean-Antillean styled white and green mansion was built in 1858, and today it's a museum where you can see Núñez' documents and personal possessions including furniture, paintings, and art. Just opposite the Casa de Rafael Núñez you'll see the chapel of Ermita del Cabrero, where the ashes of Núñez and his wife rest.
On Calle Real 41-89 in El Cabrero, Casa de Rafael Núñez is open 9am-5pm Tuesday to Friday, and from 10am-4pm on weekends. Entrance is free. Explanatory signs are in Spanish, and tours (in Spanish) are also available.
