Take a tour of Scientology's massive Los Angeles real estate empire

The Church of Scientology has a huge footprint in Los Angeles, California.

The religion, which made headlines in recent weeks via HBO's "Going Clear" documentary, owned a "real estate empire of 26 properties" worth as much as $400 million in the city as of 2011, reported the Hollywood Reporter.

While some critics say Scientology maintains a large real estate portfolio to create the impressions that it is a larger organization than it really is, there is no question the church has an impressive physical presence in the LA-area.

Business Insider visited many of Scientology's properties in the city, including the church's famous "Celebrity Centre" and a museum dedicated to Scientology founder L. Ron Hubbard.
