In the Zsámbék Basin, on the northeastern border of Tök, which was essentially built together with Zsámbék, stands the long-known ruin of the Árpád-era, presumably late 13th-century church, which is protected as a monument. It underwent conservation in 2022, and its surroundings were also landscaped.
In Hungarian some of these ruins are called "rossz templom" meaning "bad church".
