As you observe the architecture, notice the broad, stadium-like silhouette of the main sanctuary. Completed in 1973 by Sampoong Construction Industries, it was designed specifically to handle massive crowds. The main sanctuary alone can seat approximately 12,000 to 15,000 worshippers at once, though during peak Sunday services, the entire complex can accommodate many more via satellite feeds in various chapels. Inside, you will find a massive pipe organ and large video screens that provide real-time translations. One practical pointer for your visit: if you attend a Sunday service, you can obtain a wireless headset at the entrance to access simultaneous interpretation in 16 different languages, including English on channel one. The church follows a Pentecostal tradition, which means the atmosphere during worship is often incredibly energetic, featuring loud, simultaneous group prayers and rhythmic music that you might even hear echoing into the streets outside.
