A former apartment complex and hotel to the stars, the seven-story building — now the Celebrity Centre International — houses Scientology counseling and study rooms, a hotel for religious retreats and a French restaurant. The church is planning a renovation of the property, which opened in 1929. Built in the style of a 17th century French-Normandy castle, it is a city Historic-Cultural Monument.
