Parque Central is the epicenter of Antigua Guatemala, typically referred to as Antigua. This small city of less than 40,000 residents is a time capsule of Spanish history from the mid-16th through the late 18th centuries. What makes Antigua distinct is most of the once-glorious colonial buildings are dilapidated. The empty shells have been in ruins for almost 250 years. This is one of the most unique and surreal UNESCO World Heritage Sites you will ever visit.
