SAN ANTONIO -- A new coalition has kicked off a campaign to raise $15.5 million to restore and preserve the four historic missions in San Antonio.

The Las Misiones campaign has already raised $4 million toward the goal for Mission Concepcion, Mission San Jose, Mission San Juan and Mission Espada.

"These mission churches are deteriorating and in need of restoration, repair and refurbishment," Archbishop Jose Gomez said in a statement. "It cannot wait another generation. It is our responsibility and obligation to keep them standing and alive as our ancestors have done."

The missions were established nearly 300 years ago and are the oldest buildings in the region. The National Park Service operates the San Antonio Missions National Historical Park, while the Archdiocese of San Antonio cares for the church buildings.

The money will be used for things such as plaster repair, structure stabilization and art conservation.

The campaign committee includes local business and religious leaders and volunteers.
