Viljandi castle was one of the strongest castles in Livonia. The construction was started 1224 under Teutonic Order in place of a former hillfort. The crusaders of Sword Brethren conquered the hill fort at the place of later main castle in 1223. A year later, construction of stone fortifications started. Viljandi was chosen as the high seat of the order.
The convent house, a typical form of castle of Teutonic Knights, was erected late 13th – early 14th century. In the following centuries the castle was extended and fortified further. It was badly damaged in the Polish-Swedish wars in early 17th century and not repaired any more. In 18th century, the ruins were used for quarrying stones for construction work in Viljandi.
The first excavations in the castle were performed in 1878–1879. In recent decades, these have turned to almost yearly events. Currently the ruins form a popular resort area just outside of central Viljandi. An open-air stage is located in the former central courtyard.
Fisherman's Bastion is a terrace in neo-Gothic and neo-Romanesque style situated on the Buda bank of the Danube, on the Castle hill in Budapest, around Matthias Church. It was designed and built between 1895 and 1902 on the plans of Frigyes Schulek. Construction of the bastion destabilised the foundations of the neighbouring 13th century Dominican Church which had to be pulled down. Between 1947–48, the son of Frigyes Schulek, János Schulek, conducted the other restoration project after its near destruction during World War II.
From the towers and the terrace a panoramic view exists of Danube, Margaret Island, Pest to the east and the Gellért Hill.
Its seven towers represent the seven Magyar tribes that settled in the Carpathian Basin in 896.
The Bastion takes its name from the guild of fishermen that was responsible for defending this stretch of the city walls in the Middle Ages. It is a viewing terrace, with many stairs and walking paths.
A bronze statue of Stephen I of Hungary mounted on a horse, erected in 1906, can be seen between the Bastion and the Matthias Church. The pedestal was made by Alajos Stróbl, based on the plans of Frigyes Schulek, in Neo-Romanesque style, with episodes illustrating the King's life.
