Holy Trinity Church, Serbian Orthodox church in Gornji Milanovac, Serbia

Holy Trinity Church is a single-nave Serbian Orthodox church in central Gornji Milanovac, built 1860–1862 to a design by Nastas Đorđević. It has a barrel-vaulted nave, a semicircular altar apse, a shallow rectangular side choir, and a Baroque bell tower above the narthex. The facade combines pilasters and arched window wreaths with carved-stone decoration recalling the Raška school.

Construction started in 1860 under Prince Milos Obrenovic and was finished by his son Prince Mihailo in 1862. The church was built during a period when this family held significant influence over Serbian affairs.

Inside the church are kept pieces of the Takovo oak, the tree under which the Serbian national assembly met in 1815 and launched the Second Serbian Uprising against the Ottomans. Another part of the same oak is kept in Prince Miloš's residence in Belgrade. The church belongs to the Eparchy of Žiča.

A tomb of the Obrenovic family stands at the church gate and holds the remains of Duke Milan Obrenovic, brought here from Romania in 1995. Visitors should dress respectfully and behave quietly when entering this religious space.

The old iconostasis, carved by Nikola Marković in 1862, is considered artistically more valuable than the one that replaced it in the 1960s. It is now kept in the church tower, and a few original icons were cleaned in 2000.
