to the Schleswig-Holstein and Mecklenburgian possession, estates which were temporarily in the possession of the Reventlow included Good Bülk (around 1350), Gut Kaden (15th century), Gut Waterneverstorf (1592–1662), Gut Dobersdorf (in the 17th century, from 1625), Gut Altenhof (1691–1960, inherited from the family of Bethmann-Hollweg) with Wittenberg and Gut Jersbek (1840–1960), Quarnbek and Schmoel (around 1700), Hohenfelde with Kollmar (around 1700–1739), Gut Rantzau (1728–1740), Gut Emkendorf (1764–1929), Gut Kaltenhof ( 1780–1910), Gut Falkenberg (1790–1848), Gut Testorf (18th century), and Gut Farve (19th century to 1926). In Schleswig-Holstein the family is still based in Gut Damp (since the end of the 16th century), Gut Wittenberg (since 1584), Gut Wulfshagen (at Tüttendorf, since 1903) and Gut Eckhof (since 1972). In Denmark, Gram Castle was taken over or built by the Reventlow around 1470 and remained in the family until 1664. In 1673, Prime Minister Conrad Reventlow acquired the Sandbjerg Castle (1673–1930 owned by the family) with Gut Ballegård and built Clausholm Castle (owned 1690–1743). His son Christian Detlev of Reventlow acquired Brahetrolleborg on Funen (1722–1960), Pederstrup on Lolland (1725–1935) and Christianssæde on Laaland (1728–1934). His son Conrad Detlev Reventlow (1704–1750) married Wilhelmine Auguste, the sister of the Duke Friedrich Karl of Schleswig-Holstein-Sonderburg-Plön in 1731. In 1739 he acquired the Krenkerup Castle at Radsted Sogn with Nørregård and Rosenlund (1739–1793). In 1900, the estate Agerupgård in Våbensted Sogn came to the Counts Reventlow, who are still there. Commoner descendants in the female line with the name Reventlow (no title of nobility) are the families Reventlow-Mourier on Brahetrolleborg and Reventlow Grinling on Krenkerup, as well as some descendants in the cognitive line in Sweden. Coat of arms The family crest of the family is divided in the Zinnenschnitt of silver over red. On the helmet with red-silver blankets stands a gold ring (feather play) set all around with silver feathers on a short red pole. Derived area coats Elements and colours from the coat of arms of the family Reventlow appear today in some Schleswig-Holstein municipal coat of arms.
