The town of Vallendar spreads out on the right side of theMittelrhein opposing the island ofNiederwerth, where several creek valleys from theWesterwald meet the Rhine valley. It is situated 5.7 km (3.5 mi) north ofKoblenz and 12.3 km (7.6 mi) south ofNeuwied. East of Vallendar rises theWesterwald, on the other side of the river theEifel.
Vallendar is first mentioned around 830–840 AD as the property of theArchbishop of Trier; it was probably, however, of Celtic origin and a lot older (700–600 BC). In 1143 Schoenstatt Abbey was founded. In 1232 the Count ofSayn took possession of the land and began building a castle at the northern edge of the town in 1240. Its foundations today support theMarienburg.
From the 14th century the Archbishop of Trier regained more and more power over the land to become proprietor again in 1681 and in 1767 (for good). Today the Lion of Sayn and the Cross of Trier are evidence of this history in Vallendar's coat of arms.During theMiddle Ages a Palatine high court was located in Vallendar. 1802 the proprietorship went to the Count of Nassau-Weilburg; in 1815 it fell to theKingdom of Prussia. A rich business life is the reason whyFrederick William IV of Prussia grantedtown rights to Vallendar in 1856. In 1939Mallendar was added to the town. It was the scene of a military action by the 23rd US Infantry.[3] From 1954 to the 1970s numerous new construction areas were established. Since 1973 the skyline has been dominated by the "Humboldthöhe".
