Kozí hrádek, known as 'Little Goat Castle' in English, is a medieval Gothic ruin near Sezimovo Ústí in the South Bohemian Region of the Czech Republic. This historical site is significant due to its association with Jan Hus, a key figure in church reform during the early 15th century. The castle stands on a rocky promontory above the stream Kozský potok and is recognized as a national cultural monument for its connection to Hus's life.

The origins of Kozí hrádek trace back to the 14th century, with its first documented mention in 1377 when it was held by Vlček of Kozí. Ownership passed through several noble families, including the Lords of Hardegg and Jindřich I of Hradec, before being acquired by Vilém of Újezd in 1406. This marked the beginning of the Kozský family's association with the castle.

Architecturally, Kozí hrádek was a donjon-type castle featuring a rectangular stone residential tower at its core. The structure included inner and outer defensive walls, an earthen rampart topped by a wooden palisade, and a deep water moat up to 20 meters wide. Access to the castle was via a wooden bridge leading to a drawbridge at the gate tower.

The most notable period in Kozí hrádek's history occurred between 1412 and 1414 when it served as a refuge for Jan Hus. During his stay, Hus continued his reformist preaching and authored several important theological works, including De ecclesia (On the Church). The castle's significance was further underscored by its destruction in 1438 during the Hussite Wars, likely due to fire set by King Albert II of Habsburg's troops.

Following its abandonment after the wars, Kozí hrádek became a source of building materials for local villagers. Systematic archaeological efforts began in 1886 and continued into the early 20th century, revealing over 250 artifacts now housed at the Hussite Museum in Tábor. The site has been conserved since 1929 and is currently owned by Sezimovo Ústí.

Today, Kozí hrádek stands as a testament to its turbulent past and its role in religious reform history. Visitors can explore the ruins via marked tourist trails or cycle path 1026, gaining insight into the life of Jan Hus and the broader context of Bohemian religious upheaval. The site's historical significance and well-preserved state make it a compelling destination for those interested in medieval architecture and church history.

Architectural development

Kozí hrádek was originally surrounded by a moat with a palisade, featuring a two-part structure divided by a substantial stone wall. The main entrance led through an earthen rampart to the keep, which was accessible via a wooden bridge. Over time, the castle served as a source of building materials and gradually fell into ruin.

Jan Hus stayed at Kozí hrádek in the autumn of 1412 and from spring 1413 to spring 1414, where he preached and worked on his writings.

The castle likely burned down during a military campaign by Albrecht II Habsburg in 1438.

Owners

The first recorded owner of Kozí hrádek was Vlček z Kozího in 1377, followed by Jan z Hardeka from 1391, Jindřich z Hradce from 1406, and then Vilém z Újezda. The castle later became associated with Jan Hus.

Points of interest

- Despite its name meaning 'Little Goat Castle,' there is no historical evidence to suggest that goats were ever a significant part of life or symbolism at Kozí hrádek. The name likely derives from the rocky promontory it stands on, which resembles a goat's head.

- An intriguing legend suggests that Jan Hus used secret tunnels within Kozí hrádek to escape during his time there. While no physical evidence of such tunnels has been found, this story adds an element of mystery and intrigue to his stay at the castle.
