I had the amazing pleasure to attempt to a wonderful event organized in el Palacio de la Cultura. The building is already pretty impressive from the outside, the plaza with the font and the spectacular show from the doves. But from the inside, you can feel the history and transport yourself automatically to years and years of Guatemala's history. In my personal experience i did not use a tour or guide. I did it by myself by reading and previously searched for information. Is a place you should definitely visit in Guatemala city.
