This stone tablet was erected within the castle grounds to commemorate the construction of the roadway between Shuri and Urasoe Gusuku, a project of King Sho Nei. On the tablet is written that under royal command the strength of the local people made possible the construction of the road and the rainbow bridge that crosses the river. The stele was completely destroyed in WWII and reconstructed in 1999. From this point the tomb of Tamagusuku Chokun, Shurijo Castle and the Benkedake Hills can be seen in the distance.
