The Church of Santo Domingo is a baroque building founded by the Dominican Order built over a period of more than 100 years, beginning in 1560. The decoration on the inside is the work of the best artists of that period. The gilded ceiling and walls are covered in plaster statues and flowers. The yellow stained-glass window fills the interior with a golden glow every time the sun shines through it.
The under choir is a richly decorated area with an elaborated genealogical tree of the Dominican order, including numerous saints and martyrs. This is the first thing you'll see entering the church, just look up!
And don't forget to visit the Centro Cultural Santo Domingo in what used to be the Dominican Convent. Is a beautiful complex with a botanical garden, a library and museum telling the history of Oaxaca.
