Chapel

The Seattle Grace Chapel is a small church.

Grey's Anatomy, Season 5
In Before and After Addison came to pray for her brother Archer but did not know how. Callie decided to help by praying beside her (looking for guidance with Arizona and their kiss).

When Izzie was admitted to the hospital as a patient, Callie went to the chapel with Arizona to pray for Izzie, feeling guilty for all the days she had wished her dead.
