Trinity Church in Chashnikovo, Eastern Orthodox church in Chashnikovo, Russia.

Trinity Church in Chashnikovo is a four-pillar, cross-domed Orthodox church without altar apses, a rare feature for its time. Its main volume was raised in the late 17th century under the Naryshkins, who added side chapels, a refectory porch, and a small tented bell tower with carved baroque ornament. A separate brick bell tower designed by A. A. Latkov was added on the west side in 1895.

The church was first documented in 1585 as a stone church with five tops, though architectural features suggest construction closer to the early 16th century. In 1688 Chashnikovo passed to Lev Kirillovich Naryshkin, uncle of Peter I, and under the Naryshkins the dilapidated church was rebuilt in Moscow Baroque style: walls and small drums were raised, side chapels and a porch added, and a new small tented bell tower replaced the old belfry. In 1895 a separate brick bell tower designed by architect A. A. Latkov was added on the west side.

The church keeps several venerated icons, among them a Sergius of Radonezh icon with a relic and strands of his hair, and icons of the Mother of God "Skoroposlushnitsa" and of Panteleimon written and consecrated on Mount Athos. A portion of the myrrh from the relics of St Nicholas is kept in the altar.

The church stands in the village of Chashnikovo on the Alb River, in the Khmki urban district of the Moscow region. Next to it survives the red-brick building of the former parish school, built in 1898 to a design by A. A. Latkov, visible from afar beside the blue cupolas. The church is an active place of worship, so dress modestly.

The church has no altar apses, an unusual feature for its period. Its refectory preserves iconostases from the mid-19th century, while the 1895 bell tower was added to the west according to a design by architect A. A. Latkov.
