The enormous Teatro Peón Contreras was built between 1900 and 1908, during Mérida’s henequén heyday. It boasts a main staircase of Carrara marble, a dome with faded frescoes by Italian artists, and various paintings and murals throughout the building. The Yucatán Symphony Orchestra performs here Friday at 9pm and Sunday at noon throughout most of the year. See the website for more information.
