Tenczyn Castle is now in ruins. What might it have looked like?

·14 May 2026

Tenczyn Castle in Rudno is today one of the largest surviving examples of a private fortified residence in Poland. The stronghold has stood abandoned since the 18th century, when it was destroyed by a tragic fire. The picturesque remains of this magnificent complex inspired architect Michał Szymankiewicz to create digital visualisations, based on the works of Zygmunt Hendel, depicting what the building is thought to have looked like before its destruction.

Tenczyn Castle – seat of the Tęczyński family

The history of the castle dates back to the mid-14th century. The stronghold was probably built by Andrzej of Morawica of the Topór coat of arms, Voivode of Kraków and one of the closest associates of the last Piasts. The residence was built on a hill, the remnant of an ancient volcano, at an altitude of approximately 403 metres above sea level. The name ‘Tenczyn’ derives from the former Tęczyn Forest, which was cleared from 1319 onwards on the orders of Nawoj of Morawica. Originally, the spelling with the nasal ‘ę’ was used; however, with the evolution of the language and changes in spelling, the form ‘Tenczyn’ became established, whilst the family name retained its former form ‘Tęczyńscy’. The original castle was Gothic in character. It comprised defensive walls, a tower (later known as Dorota) and a residential section with a chapel. At that time, the complex served as the administrative centre of extensive estates. As early as the 15th century, the stronghold was expanded, dividing it into an upper and lower castle. A gate tower was built at that time, and the residential wings were extended with new storeys. Interestingly, some Teutonic prisoners were held at Tenczyn following the Battle of Grunwald, and the court was visited by figures such as Mikołaj Rej and Jan Kochanowski.

Renaissance reconstruction and the end of its glory

The castle’s greatest heyday came in the 16th century. Around 1570, Jan Tęczyński transformed the medieval stronghold into a magnificent Renaissance residence. Around the arcaded courtyard, stately residential wings with cloisters and decorative façades were built. Bartosz Paprocki wrote at the time that the castellan “at great expense had the castle at Tenczyn almost rebuilt from scratch”. The expansion was accompanied by the modernisation of the fortifications. From the south and west, casemate bastions inspired by the Italian school of defence were added, whilst the north-western front received a characteristic gatehouse bastion with a long embrasure gallery. In 1639, the estate passed into the hands of the Opaliński family through the marriage of Izabela Tęczyńska to Łukasz Opaliński. A dozen or so years later, the decline of the residence began. First, in 1655, the castle was seized by Swedish troops, who set fire to and plundered the building during their retreat. A valuable record of its former appearance is the plan drawn up at that time by Erik Jönsson Dahlberg. However, the reconstruction following the destruction did not restore the residence to its former status. Later, following a lightning strike and a fire in 1768, Tenczyn fell into permanent ruin. In 1784, it was visited by Stanisław August Poniatowski, and Adam Naruszewicz described the ruins as a symbol of the passing of great families.

Reconstruction by architect Michał Szymankiewicz

Despite the extensive damage and the evident loss of many of the residence’s former features, its ruins continue to inspire admiration and spark imaginings of Tenczyn’s former grandeur. The visualisations prepared by Michał Szymankiewicz attempt to recreate its probable appearance during its period of greatest splendour. The artist has combined historical materials, old engravings, surviving plans and documentation of the ruins with the capabilities of modern digital tools. In his work, he has utilised, amongst other things, graphics software and 3D modelling supported by artificial intelligence algorithms. As he emphasises, creating a reconstruction requires repeated image processing, adjustments to proportions and comparing the results with the source material. The resulting images depict a vast residence with cloisters, high roofs and an extensive system of fortifications. They make it easier to understand the scale of the former complex and the position of the Tęczyński family amongst the magnates of Lesser Poland. Importantly, the castle has never been the subject of a full excavation or investigation. It is still unknown, for example, how the oldest entrance to the stronghold ran. Despite this, the architect’s studies have attracted considerable attention from internet users and history enthusiasts.

Tenczyn Castle as a permanent ruin

For 200 years, Tenczyn has been one of the most picturesque monuments of the Kraków-Częstochowa Upland. The ruins were immortalised by Jan Nepomucen Głowacki, Napoleon Orda, Zygmunt Vogel and Kajetan Kielesiński. The surviving sections of the walls still reveal the former grandeur of the residence. Visible features include the remains of a Gothic chapel, fragments of a Renaissance attic, stone details, and massive towers and bastions. The gate tower, connected to a long embrasure gallery, attracts particular attention from researchers; it is considered one of the most interesting defensive structures of its kind in Poland. The first inventory of the ruins was carried out in 1864 by Zygmunt Hendl, though more precise measurements were not taken until 1983–1984. Several attempts were made to save the site in the 20th century. Conservation work began even before the First World War, and was resumed after 1949. Despite these efforts, the castle continued to deteriorate until it was closed to visitors in 2009 due to its very poor structural condition. Following further renovations, it was reopened to tourists in 2016.
