North of Zona 1, Zona 2 is mostly a middle-class residential district, but it's worth venturing along to Parque Minerva to see this huge open-air map of Guatemala showing the country at a scale of 1:10,000. The vertical scale is exaggerated to 1:2000 to make the volcanoes and mountains appear dramatically higher and steeper than they really are.
Constructed in 1905 under the direction of Francisco Vela, it was fully restored and repainted in 1999. Viewing towers afford a panoramic view. This is an odd but fun place, and it's curious to observe that Belize is still represented as part of Guatemala. It's an easy walk (or short cab ride) from Parque Central.
