Just behind the Temple de Santa María Natividad is the small Zona Arqueológica, with a pair of underground tombs that are fun to explore. A pair of eerie carved owls guards one of the graves containing a noble named Lord Nine Flower. He was buried along with an unidentified young man among riches that rivaled those of Tumba 7 at Monte Albán. These treasures, however, are in the archaeological museum in Mexico City. The site is open daily 9-5. Admission is $2.60.
