Royal Grand Palace, Bangkok

This part of the Wat Phra Kaew - or Emerald Buddha complex - once served as the former residence of the King of Siam and once consisted of 11 buildings; however, today only three of the original ones remain. The central building, or Chakri Maha Prasat, was built by then King of Siam, Rama V between 1876 to 1882 using British architects John Clunich and Henry C. Rose. The style of the building is a fusion of Italian Renaissance and traditional Thai architecture.

Salviati decorated the arched ceilings - originally planned as domes, but later substituted by Thai spires - of the central throne hall with 17,000 square feet of golden mosaics with depictions including various Siamese orders.

Various sources also attribute mosaic work both on the outside of the spires, as well as on the building's gables to Salviati.
