Gwaebul

Gwaebul (괘불), meaning "Large Buddhist Banner Painting," are extremely large-scale Buddhist scroll paintings found throughout Korea. They are fairly rare, and only 53 were studied between 1986 and 2001. The paintings are typically brought out only rarely for special festivals or holidays such as Buddha's Birthday or Gwaebul Festivals when they are unrolled and hung from tall poles in the temple courtyard. When not in use, "gwaebul" are stored in a box behind the altar in a temple hall.
