The first castle in Zug was probably a wooden manor house built around 1000 and owned by a ministerialis family in service to either the Counts of Aargau or of Lenzburg. Based on archeological excavations, it was built on an island between two small streams and surrounded by a wooden palisade. While the local nobleman occupied the house and island, his men built a village along the streams. Later the steams were dammed to prevent flooding.
Around the end of the 11th century, the original house expanded. A 70–90 centimeters tall stone wall was built around the house. However all the buildings inside the wall remained wooden. According to tradition, the castle was attacked and damaged during the 12th century.
In the 13th century, Zug came under the control of the Kyburgs. They founded the city of Zug (around 1200) and had the ruined castle was rebuilt in stone. A 9 by 9 m tower with 2 m thick first story walls was built. The walls taper slightly and upper story walls are only about 1.5 m thick to a height of 16 m. The tower was surrounded by two semi-circular walls to the north and east. By the end of the 13th century the town was surrounded by an, up to 16 m high, wall and additional defensive works.
When the Kyburg family died out in 1264, the city and castle of Zug were inherited by the Habsburgs. The castle living quarters were expanded and a number of buildings were added between the tower and city wall. After the Habsburg defeat at the Battle of Morgarten in 1315, Zug became a Habsburg stronghold in an increasing hostile Swiss Confederation. The surrounding cities of Zurich, Lucerne and Glarus joined the Confederation and the nearby villages began to side with the Swiss, however, Zug city remained strongly tied to the Habsburgs. When the Confederation invaded Zug, the surrounding villages immediately surrendered. After a two-week siege, Zug Castle and city fell to the Swiss. The castle was not damaged in the siege and became a Confederation castle. After Zug joined the Confederation as a full member, the castle gradually lost its importance.
Around 1555 Johannes Zurlauben had the old wall demolished and a decorative wall built around the castle. He had a half-timbered structure built on the west side of the tower. In the 16th century the old Habsburg living quarters were expanded and connected to the Zurlauben structure.
The castle was purchased by the municipality of Zug in 1945 from the Hediger family and later renovated in 1982. Recently, the castle contained the Zug town and cantonal museum's permanent collection along with other exhibits. In 2012, the museum was closed for refurbishment and re-opened in November 2013 with a new permanent collection.References:
The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends. One of them narrates the origin of the name of castle derived from that of jester Becko for whom the Duke Stibor had the castle built.
Another legend has it that the lord of the castle had his servant thrown down from the rock because he protected his child from the lords favourite dog. Before his death, the servant pronounced a curse saying that they would meet in a year and days time, and indeed precisely after that time the lord was bitten by a snake and fell down to the same abyss.
The well-conserved ruins of the castle, now the National Cultural Monument, are frequently visited by tourists, above all in July when the castle festival takes place. The former Ambro curia situated below the castle now shelters the exhibition of the local history.
