The church is located deep in the woods. It is one of the entry points to the abandoned mines, and is used by Grunkle Stan, Soos, Dipper Pines, Mabel Pines and Old Man McGucket to track the pterodactyl. The creature had been using the building as an entrance and exit to the outside world and the mines where its nest was. The group finds many prehistoric dinosaurs preserved in amber in the mines below. The church is mostly destroyed by a geyser later.
The church is old and run down, with large sections of moss covering the roof. Most of the stained glass windows are broken and/or boarded up. The inside is covered in more moss and crawling vines. The walls are cracked, with parts exposing the underlying brick. Most of the support beams are broken and have fallen onto the floor. There is a large hole in the wooden floor that leads to the abandoned mines. The church also has a piano and two coffins. Many of the pews are old and crooked, a few are even completely destroyed.
