The chapel is located in a scenic position elevated above the valley bottom on the north side of the middle Gartetal. It is visible remnant of a once larger settlement Wittmarshof. Originally there was even the schom mentioned in the 11th Anniversary village Wittmarshausen. 1451 sold the lords of Uslar (on castle Neuengleichen) as landlords the village to Landgrave Ludwig I of Hesse. Witmershusen thus belonged to the Hessian exclave of the office Neuengleichen. In 1548 here a Vorwerk, i. a manorial farm, was built, you have probably abandoned the previous village. A few years later moved the official residence of the decaying castle Neuengleichen down to the Gartetal to Wittmarshof and 1575 was erected for a mansion. In 1816, the Hessian Office Neuengleichen came to the Kingdom of Hanover and when the office in 1825 was completely dissolved, also for the official residence Wittmarshof came to an end. Structural remains of the village Witmershusen or the Hessian Vorwerks and Amtshofes are almost no longer available. Thus, already in the Thirty Years' War, considerable destruction. Larger parts of the Vorwerk were demolished in 1870 and at the beginning of the 20th century burned down more buildings.
Today, the chapel Wittmarshof striking last certificate from the time of the official residence. It was built around 1580/1600 on a massive sandstone basement, as a chapel of Hessian introduced Protestant-Reformed faith. The truss gable is a bit younger. The bell in the Dachreiter is dated to 1696, the weather vane dates from 1819. Outside the chapel was formerly a small cemetery, of which there are still grave plates available, such as the officials Frohn and Scheufler.
The chapel was finally restored after years of effort between 1981 and 1983, with the participation of the vocational school II in Göttingen.
