Heiligengrabe
Heiligengrabe is a municipality in the Ostprignitz-Ruppin district, in Brandenburg, Germany. Geography. The municipality counts 13 villages ("Ortsteil"): Blandikow, Blesendorf, Blumenthal, Grabow bei Blumenthal, Herzsprung, Jabel, Königsberg, Liebenthal, Maulbeerwalde, Papenbruch, Rosenwinkel, Wernikow and Zaatzke. Architecture. Abbey. Heiligengrabe Abbey (literally in ; formerly also known as Techow) was founded here as a Cistercian nunnery in 1289 by Heinrich, Bishop of Havelberg and the Margrave Otto of Brandenburg, initially for 12 nuns. It held an important relic in the form of a Bleeding Host which, so it was said, had been violated in a host desecration by a Jew. The nunnery  acquired considerable wealth and estates in the area, partly through the revenue from pilgrims to the Bleeding Host, and partly through donations from the noble families round about, especially when one of their daughters entered the convent. Among the nuns of local great houses were members of the families Gans zu Putlitz, von Quitzow, von Rohr, von Winterfeld and von Blumenthal. Some of the abbesses were great characters. The Abbess Henriette von Winterfeldt had a quarrel with the Duke of Mecklenburg, who refused to pay a debt to the abbey. So she borrowed a large artillery piece and declared war  on Mecklenburg, bombarding it across the nearby frontier. At the time of the Lutheran Reformation, Abbess Anna von Quitzow would have nothing to do with the new denomination, and refused to pay tax. After the Reformation the prior function of the nunnery, to provide sustenance for unmarried women mostly from local noble families, wasn't to be given up with its secularisation. So the formerly Roman Catholic nunnery turned into a Lutheran women's convent (, more particular: Damenstift , literally in ), with its conventuals now called secular canonesses ("Stiftsdamen"). The canonesses of nobility were obliged to show sixteen quarterings in their  arms before being permitted to enter. Other infrastructures. In Heiligengrabe is the Blumenthal Observation Tower.
