No one knows for sure when the rear hall was first constructed, but a plaque hanging in the temple tells that Matsu safely brought home a convoy of ships belonging to the Chuanchou Guild in 1819, which presumably means it was built before that time.
這個後殿究竟是何年建成，目前已沒有詳細資料可以考證，然而一般推測大概是在乾隆末至嘉慶初年間，因為嘉慶廿二年艋舺泉郊曾在海上遇難，祈求媽祖保佑後，得以化險為夷，安全歸來之後就在後殿奉獻了一個大匾額，以為向媽祖謝恩。
