Преображенский храм, Orthodox church in Dyatkovo, Bryansk Oblast, Russia

The Transfiguration Church in Dyatkovo was a stone church with a bell tower built in the Greek style, consecrated in 1810. In 1838 two symmetrical side chapels were added, and in 1845 the church and bell tower were rebuilt in the Italian style. A side chapel of St. Basil the Great, cast from pig iron above the Maltsov family crypt, was completed in 1848. The iconostases were decorated with white embossed crystal from the Dyatkovo crystal factory.

The stone church with a bell tower was built between 1807 and 1810 at the request of I. A. Maltsov, and in 1810 the parish of Spasskoye was transferred to Dyatkovo. The Maltsov family rebuilt it in 1838 and 1845, and in 1848 a side chapel of cast-iron blocks was completed over their family crypt. Closed in 1929, the church was soon dismantled.

The church's name comes from the Feast of the Transfiguration, and its history is tied to the Maltsov family, who funded its iconostases. The icons for the new iconostasis were ordered from the Saint Petersburg Academy of Arts, and the iconostases were decorated with white pressed crystal from the Dyatkovo factory. Icons such as "The Presentation of the Virgin" and "The Last Supper" by the artist Lavrov drew particular attention.

The church stood in the town of Dyatkovo, Bryansk Oblast, until it was closed on 21 October 1929 and dismantled a few years later; no building survives on the site. Surviving interior pieces — a multicoloured glass candlestick, a lampada and one decorative element of the crystal iconostasis — are held in the permanent exhibition of the Dyatkovo Crystal Museum.

The church's iconostases were covered in white, embossed transparent crystal made at the Dyatkovo crystal factory, and the icons for the new iconostasis were ordered from the Saint Petersburg Academy of Arts. A multicoloured glass candlestick, a lampada and one decorative element of the crystal iconostasis survive and are shown in the Dyatkovo Crystal Museum.
