Although the question does not provide any reference or context at all, I can say that the most interesting time or place you heard about this year was the Mayan territory in the Yucatán Peninsula in México, where the Mexican President Andrés Manuel López Obrador supported the construction of a railroad that is going to have stops in every important Mayan archeological site in southern Mexico, such as Palenque, in the state of Chiapas, Tulum, next to Cancún, in the state of Quintana Roo, or Chichen Itza, in the state of Yucatán. This would be one of his most important projects as a President because it will create a great touristic attraction for the people to visit and learn about this great Mayan culture.
