Gal Vihara is a group of beautiful Buddha images that probably marks the high point of Sinhalese rock carving. They are part of Parakramabahu's northern monastery. The Gal Vihara consists of four separate images, all cut from one long slab of granite. At one time each was enshrined within a separate enclosure. You can clearly see the sockets cut into the rock behind the standing image, into which wooden beams would have been inserted.

The standing Buddha is 7m tall and is said to be the finest of the series. The unusual position of the arms and sorrowful facial expression led to the theory that it was an image of the Buddha's disciple Ananda, grieving for his master's departure for nirvana, since the reclining image is next to it.

The fact that it had its own separate enclosure, and the later discovery of other images with the same arm position, has discredited this theory and it is now accepted that all the images are of the Buddha.
