The Thai Sala (or Siamese temple) in the spa gardens is one of two Thai Salas situated in the spa town of Bad Homburg. Both of them stand for the more than 100-year-old friendship between Bad Homburg and the Thai royal family. King Rama V, also known as King Chulalongkorn, spent several weeks recuperating in the spa town back in 1904. Happy to have hosted him and his entourage, Bad Homburg festively inaugurated a mineral source that they had previously drilled and named it after the king in his honour. King Chulalongkorn showed his gratitude by donating to the City a small temple ornately covered in gold leaf, which meant to serve as a roof for the fountain. The actual inauguration took place in 1914 without King Chulalongkorn being present, as the regent had in fact died in 1910. In keeping with the guidelines of the creator of the spa gardens. Peter Josef Lenné, the first Thai Sala was not erected at the Chulalongkorn Source, but at its present-day position in the northwest part of the spa gardens. Bad Homburg is known to be the only city outside of Thailand to be the home of two Thai Salas.
