The city has had two destructive earthquakes in the 20th century. Hurricane Mitch caused further destructions in 1998. Many old buildings were damaged or destroyed in these earthquakes, and new streets and monuments were built in their place. In general, addresses are rarely used to give directions. Instead, people usually use monuments to tell where a certain place is. The problem with that approach is that sometimes, the monuments themselves were destroyed. Therefore, foreigners often have problems finding their way around the city.
