Evangelische Dreifaltigkeitskirche, Protestant church in Darmstadt-Eberstadt, Germany.

The Evangelische Dreifaltigkeitskirche stands on a raised church hill in Darmstadt-Eberstadt, reached by broad stone steps with a metal handrail. Its white tower carries a red-numeral clock face, a single arched window with dark glazing, and a steep dark grey spire topped by a small cross. The flat-roofed nave was extended eastward with rectangular niches in 1961, and stronger columns divide the interior into a wide main nave and a narrow south aisle.

A church in Eberstadt is first documented around 1260, when Konrad Reiz von Breuberg, builder of Frankenstein Castle, endowed a soul mass there. In 1523 the 26-metre tower was built and adorned with the coats of arms of Hans and Philipp von Frankenstein and their wives. The nave was enlarged by about half in 1604; Friedrich Pützer's thorough rebuilding of 1912 gave the church its present form, and it has borne the name Dreifaltigkeitskirche only since 1960.

The church was simply called the "Eberstadt Church" until 1960, when it received the name Trinity Church; until 1911 it was the village's only church. The Lords of Frankenstein donated a golden communion chalice in 1506 and the bell "St. Anna" in 1512. A tower clock with quarter-hour strike is documented since 1725.

The church stands on a hill above broad stone steps with a metal handrail, reached from the Heidelberger Landstraße; the 1930 community house is next door at number 311. A red sandstone memorial a few metres southwest of the church marks the site of the old Eberstadt cemetery. The tower clock has struck the quarter-hours since 1725.

A red sandstone monument a few metres southwest of the church marks the site of the old Eberstadt cemetery, which once lay on the church grounds. Its front bears a metal plaque and its back a carved inscription in the sandstone.
