It was founded in the 14th century and is listed as a protected monument in Poland.

[1] According to historian Paul Crossley who referenced chronicler Jan Długosz, the St. John parish church was a "royal foundation" that was created in 1360, around the time when King Casimir the Great expanded the entire town of Radom in the 14th century.

[3] The site was originally in close proximity to the market square and castle.

[5] The chapel features a polychromed vault and was endowed by the Kochanowski family.

In 2020, the parish received a grant of 100,000 zlotys for renovations from the Mazovian Voivodeship Conservator of Monuments.
