University of Florida archaeologists have uncovered the foundation of what they say is a more than 330-year-old stone church in St. Augustine.

Archaeologists say it's the oldest church of its kind in the state.

The church is believed to have been built in 1677. The foundation was found on the site of the first and longest-lasting of the Spanish missions in Florida. After English raiders destroyed the church in 1728, the ruins were buried and forgotten.

The site is now home to a modern church and chapel.

Florida Museum of Natural History researcher Gifford Waters says the foundation will be covered back up after the archaeologists finish their work next week. The foundation's size and shape will be marked to tell visitors about the discovery.
