The Annunciation Church is a Catholic church located at the corner of Texas and Crawford in downtown Houston, Texas. Annunciation Church sprung from the congregation at St. Vincent's, Houston's first Catholic church. In 1866, Father Joseph Querat and Galveston Bishop Claude M. Debuis believed the congregation was outgrowing the old building and started planning for a new one. The congregation chose the name for the planned building, "Church of the Annunciation." Nicholas Clayton designed the building that was dedicated on September 10, 1871. The bell tower was added later in 1871 and the twin towers were added in 1884.
