Knights Hospitaller
The Order of Knights of the Hospital of Saint John of Jerusalem (; ), also known as the Order of Saint John, Order of Hospitallers, Knights Hospitaller, Knights Hospitalier or Hospitallers, was a medieval and early modern Catholic military order. It was headquartered in the Kingdom of Jerusalem, on the island of Rhodes, in Malta and St Petersburg.
Templum Domini
After the completion of the purpose-built royal palace near the Jaffa Gate, the King of Jerusalem gave the building to the Knights Templar, who maintained it as their headquarters. The Dome was indicated on the reverse of the seals of the Grand Masters of the Knights Templar (such as Everard des Barres and Renaud de Vichiers), and it became the architectural model for Templar churches across Europe.
