The monastery is named after the Relics of the True Cross, which were brought to the site according to tradition by King Bolesław the Brave.
The crypts contain the mummified body of Prince Jeremi Wiśniowiecki, a 17th-century Polish nobleman and military commander.
Łysa Góra, the mountain on which the basilica sits, is famously associated with folklore legends about 'witches' gatherings'.
The monastery was the oldest in Poland for many centuries, predating the establishment of the Cistercian order in Jędrzejów.
The basilica's current structure incorporates walls from the medieval Romanesque period.
In 1944, the monastery's tower was destroyed by German artillery during World War II; it was meticulously reconstructed in the early 21st century.
The interior contains a notable late-Baroque high altar made of black marble.
The monastic complex includes a museum of the Świętokrzyski National Park, documenting the local geology and history.
Bazylika Trójcy Świętej is a sanctuary located on Łysa Góra in the Świętokrzyskie Mountains, housing relics of the True Cross. Founded in the 11th century, it is historically linked to the Benedictine Order and currently managed by the Missionary Oblates of Mary Immaculate. The basilica serves as the centerpiece of the Święty Krzyż monastic complex, which includes a museum and crypts. The current Baroque architecture dates primarily to the 18th century, following several reconstructions after fires and military conflicts. The site is a significant destination for religious pilgrimage in central Poland. The monastery complex also features a distinctive tower and panoramic views of the surrounding Świętokrzyski National Park. The crypts contain well-preserved mummified remains of historical figures, including Prince Jeremi Wiśniowiecki. It is one of the oldest sacred sites in the country.
The observation terrace at the Gołoborze viewpoint provides the most expansive shot of the forest landscape.
Wear comfortable, sturdy walking shoes as the approach to the sanctuary involves walking on steep, rocky trails within the forest.
Visit the crypts to see the historical mummies, which are accessible to the public for a small fee.
Plan extra time to walk to the nearby Gołoborze observation deck to view the unique rock scree formations of the Świętokrzyskie Mountains.
Do not attempt to drive your private vehicle all the way to the sanctuary gates, as general access is restricted; use the designated parking areas at the base of the mountain.
The sanctuary is accessible year-round, though the forest trails leading to the site may be icy or difficult to navigate during winter.
Maintain a quiet, respectful tone inside the basilica; modest attire covering shoulders and knees is expected.
