Crystal Cathedral is a Protestant church located in Garden Grove, California. It was founded in 1955 by Robert H. Schuller, who was a televangelist and author. The church is known for its iconic glass structure, which was designed by architect Philip Johnson and completed in 1980.

The Crystal Cathedral is a 128-foot-high glass building that was designed to resemble a crystal structure. The building is made up of more than 10,000 panes of glass, and it is supported by a steel frame. The church seats over 2,700 people and has a large pipe organ with over 16,000 pipes.

In addition to its architectural design, the church is also known for its music programs, which include a large choir and orchestra. The church has also been the site of several notable events, including the funeral of former President Richard Nixon in 1994.

The Crystal Cathedral was the home of the Hour of Power, a weekly television program that was hosted by Robert H. Schuller. The program featured sermons, music, and interviews with notable individuals. The Hour of Power was broadcast to millions of viewers in over 180 countries.

In 2012, the Crystal Cathedral filed for bankruptcy due to financial difficulties. The property was eventually sold to the Roman Catholic Diocese of Orange, and it is now known as Christ Cathedral. The cathedral underwent a significant renovation and was reopened in 2019.

Today, Christ Cathedral serves as the main place of worship for the Roman Catholic Diocese of Orange. The cathedral hosts a variety of events and programs, including Masses, concerts, and community events. It remains an iconic landmark in Garden Grove and continues to attract visitors from all over the world.
