This paper presents a study of a temple, known as the Lo tsA ba lha khang, in the peripheral border area of Kinnaur, in northern India. The temple may have been constructed as early as the 9th century. After a brief review the of the area of Ribba, the author gives a detailed description (including floorplans and drawings) of the architecture of the temple. Local tradition associates the temple with the famous translator Rinchen Zangpo (rin chen bzang po). A translation of a local song about Rinchen Zangpo, recorded by Veronika Hein, is included in an appendix. (Ben Deitle 2006-05-03)
