During the 12th century, there appears to have been a tower and wooden fort at the site of the present Erpeldange castle. In the 13th century, Frederic and Gerard d'Erpeldange, the first lords of Erpeldange, built a fortified stone castle guarding the valley at the point where the River Sûre meets the Alzette. The property passed successively into to the hands of the Counts of Vianden, and the Brandenburg-Outscheid and von Moestroff-Kerpen families.
Through marriage, the Gondersdorf family inherited the castle and in 1630 transformed it into a luxurious residence for their daughter. In 1677, it was inherited by Charles François baron de Failly de Sancy and Marie Marguerite de Giraldin. By that time, it was no longer of any military value as a quiet park had replaced its defences. Abandoned by the Prel family in the 19th century, it was used as a rectory. During the Second World War, the castle was damaged as a result of its use first by the Germans and then by American troops.
The castle changed hands a number of times until it was acquired by the State in 1983. The commune's administrative offices have been housed there since 1987. The building still contains two fine Renaissance fireplaces.
References:Červená Lhota castle stands at the middle of a lake on a rocky island. Its picturesque Renaissance building is a destination of thousands of tourists every year. Its name Červená Lhota meaning 'red lhota' can be explained by the colour of the château"s bright-red roof tiles. There is also a park, where the Chapel of the Holy Trinity is located.
The existence of an original fortress on the site of today"s château is assumed from sometime around the middle of the 14th century. It was built on a rocky granite outcrop, which, after the damming of a stream and the filling up of a fishpond, became an island. The first written source is an entry into the land records from 1465, mentioning the division of the property of deceased Ctibor of Zásmuk between his two sons Petr and Václav.
