The first mass at St. Dominic's Catholic Church was conducted on St. Patrick's day in 1854. The church, then located at the corner of 4th East and J streets in Benicia was not yet completed. The current parish was built when the congregaton outgrew the old building. Today, St. Dominic's boasts a registered congregation of nearly 2,000 people. Services are for all ages, so there is no child care on Sunday mornings.
