Tegucigalpa (Hondurans in general, and people familiar with the city, shorten it to "Tegus", while most locals actually use the full name...) is a great example of Central American urban sprawl gone amok, spread out across very hilly terrain.
Of course, the city, a 400 year-old mining center, has a depth that is there for those with time and nerve to find it. It has a plethora of interesting, if decaying, old colonial buildings, and many old stone streets winding intriguingly up steep hills to hidden parks, stone steps, and old houses.
