The Freedom Square ("Vabaduse väljak") is the main square of Tallinn and also the site of the War of Independence Victory Column. The square has had several names during history. The five-meter monument to Peter the Great was erected there by the Russian empire in 1910 and the square was named after him. After the Estonian independence in 1922 the statue was melted and recycled and the square named as the Freedom Square.
About 20 years later, in 1944, the Soviet Union occupied Estonia and in a few years after the area was named as Victory Square. After the Estonia's new independence, the name was restored once again to Freedom Square.
The square is bounded on the east by St. John's Church (built 1862-67), on the south by Kaarli Boulevard and an underground shopping center (2008–09), and on the west by aVictory Column (2009) commemorating the Estonian War of Independence 1918–1920.
The Square has quickly become a meeting place due to its location right next to the Old Town and Toompea (the Cathedral Hill). The majority of the underground pedestrian zone is under the AHHAA Science Centre, Youth Information Point, an exhibition of the history of the Square and archaeological finds.

Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
