Mayan paintings inside the Merida Government Palace.
The site Yucatan Today has a detailed briefing on all the paintings adorning the halls and rooms of this public building.
The daily free walking tour begins here every morning at 9:30 in front of the Palacio de Gobierno (Government Palace) on Plaza Mayor, and visits every major building surrounding the Plaza. They cover all the paintings and their history as well. On my tour I was joined by a Spanish and French couple, and my guide spoke all languages.
