Either Lütold V von Regensberg or his son Ulrich established the fortified town of (Neu)-Regensberg around 1250. Ulrich died around 1280, and his son Lütold VIII had to sell Regensberg to Habsburg-Austria in 1302. The Habsburgs mortgaged the castle and town several times, and in 1407 the so-called Herrschaft Regensberg was acquired by the city of Zürich. From 1417 the castle became the seat of the bailiff of the bailiwick of Regensberg. On 6 June 1443 the council of Zürich forced their troops and the citizens to defend the fortified town, three days later the castle was conquered during the Old Zürich War by Zürich's contrahents, but not destroyed, and some months later manned again by Zürich troops.
On 9 September 1540 the town, but not the castle, was destroyed by fire, because it was separated from the Oberstadt by a ditch. The upper castle was rebuilt in the following year. From 1689 the castle and the upper town were fortified according to then modern standards. On 13 March 1798 the French revolutionary troops forced the council of the city republic of Zürich to abdicate, and the country bailiwicks were dissolved. After the end of the short-lived Helvetic Republic, Regensberg became the district capital, and the castle was the seat of the cantonal authorities, and in the main building there was the county jail until 1863.
Regensberg was designed as a fortified castle town and built by then modern contemporary criteria. The so-called upper castle (Oberburg) comprises a rectangular plaza as main square which is surrounded two rows of houses, and into the limestone a 57 m (187 ft) deep water well was carved. The lower castle (Unterburg) or lower town (Unterstadt) was probably built in the 14th century nestled at the castle's hill outside of the town wall. Therefore, it was not involved in the modernization of the upper castle in 1689.
Nowadays, the castle belongs to the Regensberg Castle Foundation. The round tower is still open to the public and offers a spectacular panoramic view of the surrounding region. In addition, information panels inside the tower relate the history of the small country town of Regensberg.References:
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.
