Set aside at least a couple hours for this wonderful sight. We hired one of the local guides who go in depth while they walk you through the murals. The murals are in the State Government building also known as Palacio de Gobierno, that's where the Governor's office are usually located. The murals are a wonderful depiction of Tlaxcala's history since before the arrival of the Spaniards until after the conquest. You can see the stories, the traditions, the heroes, the battles. the arrival of the Spaniards, the alliance with Spain, the legends, the markets and many other details of everday life since pre hispanic times. The painter was Desiderio Hernández Xochitiotzin a native of Tlaxcala who took more than 40 years in the making of the murals starting in 1957 and not being able to finish them until his death in 1997. During this years while he was painting he was researching and investigating new archeological discoveries which were incorporated in his paintings. The murals are wonderful and they became one of the highlights of my trip through Mexico this year.
