PLAZA DE LA TRINIDAD
It is so named since 1643, when the Church of the Holy Trinity was completed build. Later, being independent Cartagena of the Spanish Crown, the council decided to be called Freedom Square, in honor of the citizens of Gethsemane neighborhood gathered in the plaza and who attended the November 11, 1811 in the revolution that would result in the signing of the Declaration of Independence. Also note that from the churchyard itself the leaders exhorted the enraged people.
