The Holy Trinity Church (Kostel Svyatoi Triytsi) is a Dominican church in the old town of Kamianets-Podilskyi, built in the mid-17th century with a distinctive twin-tower baroque facade. The church stands on the main street of the old town and is one of the most architecturally refined buildings in the city, its proportions more careful and its stone carving more elaborate than the city's other churches.
Like many of Kamianets-Podilskyi's religious buildings, the Holy Trinity Church has changed denominations several times over the centuries — Catholic, then briefly Orthodox, then Catholic again. It is currently used as a concert hall and for cultural events, which gives visitors the opportunity to see the interior without a religious service. The building is generally open during the day and is a good place to appreciate the quality of 17th-century Polish ecclesiastical architecture.
