There was a 13-metre (43 ft) deep well in the middle of the fortress and the territory held about 90 structures with furnaces for accommodation built with limestone floors and foundations.

The terms offered by Volquin, the Master of the Livonian Brothers of the Sword were: accepting Christianity and giving hostages.

The hostages were freed at the request of the envoys of the Danish king Valdemar II who had taken control over Northern Estonia.

They asked that the hostages be turned over to them, as part of Estonia already belonged to the king of Denmark since it was promised by the bishops of Livonia.

Master Volquin, unaware of the promise, honored the king of Denmark and the request under condition that the rights of the Livonian Brothers of the Sword shall not be diminished thereby and returned the hostages to their fathers.
