A katakana noun for a Christian church, especially likely in names, translations, or English-flavored contexts. 教会 is the more ordinary general word in Japanese.
駅前のインターナショナル・チャーチで英語の礼拝がある。
There is an English service at the international church in front of the station.
Used for counting individual church buildings, though 所 sounds more natural.
