I didn’t have a lot of free time to sketch on my own in Argentina, but here are two views of Córdoba from our first day there. The first is of the Plaza de la Independencia as seen from our hotel room.
The second drawing is of the Plaza San Martin, center of the historic district and featuring a statue of José de San Martín, the Argentine general who lead the successful struggle for independence. In the background, you can see the 16th century Cathedral.
