1 – Paide Castle
A castle was built in Paide by order of Konrad von Mandern, master of the Livonian Order, sometime in 1265 or 1266. With its six storeys, the tower has always been the core of the castle complex. The fortress was strengthened during the 14th and 15th centuries, when the surrounding walls were enlarged and towers added.
During the Livonian War, the castle was repeatedly besieged by Russian troops, and in 1573 it was occupied by troops loyal to Ivan the Terrible. In 1895-1897 restoration work was carried out on the central tower and some other parts of the castle. However, in 1941, during World War II, retreating Soviet troops blew up the central tower and it was not repaired until after Estonia regained its independence, in 1990-1993.

In 1347 King Valdemar IV of Denmark sold Northern Estonia, including Narva, to the Livonian Order, who rebuilt the building into a convent building according to their needs. The stronghold has for the most part preserved the ground plan with its massive wings and a courtyard in the middle.
The Herman Tower was also completed at the time of the Order, necessitated by the establishment of Ivangorod Castle by the Russians to the opposite side of the Narva River in 1492.

In the 17th century, the castle was no longer used as a defensive building by the Swedes who now ruled the Swedish Estonian Province.
