Himmelpfort Abbey, Cistercian monastery in Fürstenberg/Havel, Germany

Himmelpfort Abbey is a former Cistercian monastery in Himmelpfort, now part of Fürstenberg/Havel, between the Stolpsee and Haussee lakes. Of the complex, the monastery church, a farm building known as the brew house and the monastery wall survive as ruins and are protected monuments. The convent was not established before 1308.

Margrave Albrecht III of Brandenburg founded the monastery in 1299 as the third daughter house of Lehnin Abbey; the convent was not established before 1308. Its initial endowment comprised six villages, around 100 hides, ten mills and fishing rights on 39 named lakes. It never matched Lehnin or Zinna in importance. Secularised in 1541, the estate passed to Hans von Arnim-Boitzenburg and later to Adam von Trott.

The Latin name coeli porta, Gate of Heaven, is one of the titles of the Virgin Mary in the Litany of Loreto. The ruined east part was reused in 1663 to build the village Lutheran church, which still serves Himmelpfort. The abbey park is known for its white poplars and large-leaved lindens.

The grounds are open to visitors who can explore the ruins by following marked walking paths throughout the site. Visit during warmer months when the paths are dry and the lakeside surroundings are easiest to navigate on foot.

The abbey's brew house, a separate economic building, was destroyed by fire on 21 August 2010; only its ruins remain. The east part of the ruined abbey was reused in 1663 to build the Lutheran village church, which still serves the parish today.
