Cathedral Basilica of St. Augustine.

Located in St. Augustine's Historic Downtown region, the Cathedral Basilica of St. Augustine is the oldest Catholic Church in the city and the oldest parish in the country.
In 1565, Padre Lopez de Mendoza Grajales presented a cross to Pedro Menendez de Aviles as he stepped onto the banks of La Florida. Menendez first kissed the base of the cross, then kissed the base of the Spanish flag. Thus, the city of St. Augustine and the Parish of St. Augustine were founded in the same breath. Then, the first Catholic mass in the Continental United States took place.
However, the cathedral's original structure only dates back to the 1700s, during the Spanish and British Colonial periods. The present permanent structure was finalized in 1797.
