Santuario La Asunción de María stands in Cupilco, a short ride from Comalcalco, and is one of the most memorable churches in the area. Its bright painted facade mixes Catholic forms with local colour and natural motifs, so it feels much more Tabasco than standard colonial stonework.
It is worth the detour if you have your own transport or a taxi for the afternoon. Pair it with the archaeological site and cacao stops for a fuller picture of the region.
