This founding, however, was irregular as no town council was formed nor were town officials appointed, as well as lacking some other juridical requirements for an official founding. As a consequence, the official founding only occurred about eight months later, on 27 April 1539, in a site close to one of the recreational lands of the ''zipa'', called Theusa or Theusaquillo. This official founding involved an official ceremony appointing a council and officials, and the demarcation of streets and lands, and in it fellow conquistadores Sebastián de Belalcázar and Nikolaus Federmann were present. While this was the official date of founding, traditionally it is the 6 August 1538 that is considered the date of the actual foundation.
