Newar Buddhism is characterized by its extensive and detailed rituals, a rich artistic tradition of Buddhist monuments and artwork like the
chaitya (stupa), Baha and Bahi monastic courtyards, statues,
paubha scroll paintings and
mandala sand paintings, and by being a storehouse of ancient Sanskrit
Buddhist texts, many of which are now only extant in
Nepal. According to the authors of
Rebuilding Buddhism: The Theravada Movement in Twentieth-Century Nepal: "Today traditional Newar Buddhism is unquestionably in retreat before Theravada Buddhism." Chachā (Charyā) ritual song and dance and
Gunlā Bājan music are other artistic traditions of Newar Buddhism. Although Newar Buddhism was traditionally bound to the Kathmandu Valley and its environs, there is at least one new Newar Buddhist temple in
Portland, Oregon. ==Outdoor festivals==
