The Phra Sawet Kudakhan Wihan Yot (พระเศวตกุฏาคารวิหารยอด) or the Wihan Yot extends northwards from the terrace. The building, a vihara, serves as a Buddha image hall, and was first built by Rama III to house many important Buddha images. The building has a cruciform plan and is topped in the middle of the roof with a tall spire in the form of a crown. The spire is decorated with coloured porcelain in floral designs. The top of the window arches display the royal cypher of Rama V under a crown; this indicates that vihara was restored by the King. Bronze figures of Tantima birds—birds with a human torso and Garuda head—guard the entrances on the west and east sides. The doors of the vihara feature mother-of-pearl inlay and were taken from Wat Pa Mok in Ang Thong Province.
