Bukit Rhema, universally known as Gereja Ayam (Chicken Church), is a surreal abandoned prayer house in the forested Menoreh Hills about 2 km west of Borobudur. The building was constructed from the 1990s onward as a non-denominational house of prayer, but was never finished and fell into disuse before being rediscovered by tourists as a peculiar attraction.
The structure is designed in the shape of a dove (or, more convincingly, a giant chicken): the head forms an observation tower at the top, accessible by a narrow internal staircase. The view from the rooster's comb takes in the Kedu Plain, Borobudur's pyramid visible among the trees below, and the volcanic peaks around it. Visits require a modest entrance fee; go early morning for the best light and thinnest crowds.
