The castle tower is a fragment of the oldest building in Tukums. It is believed that the construction of the castle in Tukums was commenced in 1277 by the Livonian Order. The castle was surrounded by a 7.5 m tall and 1.6 m wide stone wall. The castle defence was ensured by an artificial, deep moat and its position on the high bank or the River Slocene. Only a small stone wall fragment has been preserved from the castle, but the castle tower built in the 18th century in turns hosted premises for a prison and the caronal stocks (granary). Nowdays, it hosts the history museum of Tukums town, telling about the town's history from the ancient times up until the modern day.References:
Bouillon Castle was mentioned first in 988, but there has been a castle on the same site for a much longer time. The castle is situated on a rocky spur of land within a sharp bend of the Semois River.
In 1082, Bouillon Castle was inherited by Godfrey of Bouillon, who sold it to Otbert, Bishop of Liège in order to finance the First Crusade. The castle was later fitted for heavy artillery by Vauban, Louis XIV's military architect in the late 17th century.
The castle is entered over three drawbridges. The main courtyard then leads to the ducal palace with its 13th century Salle Godefroy de Bouillon. From there visitors climb up to the top of the 16th century Tour d’Autriche for a breathtaking panorama of the town and river, before they way back via the torture chamber, citerns and dungeons, and past the 65m deep well Shaft.
