The relation between Borobudur Temple with Mendut and Pawon Temple is portrayed from Waisak ritual. It starts from Mendut Temple to Pawon Temple and ends in Borobudur Temple. The relation of three temples resembles an imaginary line. The line also creates a speculation over an ancient traditional path that connect the three temples. A traditional path that crossed Progo River in the east of Pawon Temple. The ritual from Mendut Temple is assumed to be carried on to Pawon Temple by using a traditional bridge to cross Progo River. The bridge was also served to reach Brojonalan Village. The relief in Borobudur Temple indirectly informs us about the technological prowess of the past society such as traditional wooden or bamboo bridge.
