Iglesia Santa Bárbara
This combination church and fortress, the only one of its kind in Santo Domingo, was completed in 1562. It is a fine example of colonial Spanish architecture, and not as touristic as the cathedrals. Mass is held on Tuesday and Thursday evenings from 6 to 7, and on Sunday mornings from 8 to 9 and 10 to 11. The site is open every day but the church is open to the public only on days mass is held.
