Hörde Castle, located in the Dortmund district of the same name, is a former moated castle whose origins date back to the 12th century. It sits on the shores of the artificially created Phoenix Lake 🌊, which was built to revitalize the disused Phoenix-Ost steelworks ⛓️. During World War II, Hörde Castle was partially destroyed and subsequently rebuilt. In 2001, the Phoenix-Ost plant ⛓️ was shut down, leading to the demolition of the production facilities. Starting in 2008, archaeological excavations were carried out on the grounds of Hörde Castle, followed by extensive roof and structural renovations. 📷 A great photo opportunity 📸

The excavations at Hörder Castle, carried out by Dortmund City Archeology between 2007 and 2009, uncovered extensive and significant archaeological traces that shed light on the castle's 800-year construction history. Particularly noteworthy is the discovery of a bastion from 1500, which indicates that the medieval castle complex was converted into an early modern fortress. These discoveries provide new insights into the military and administrative significance of Hörder Castle over the centuries.

The former aristocratic residence Haus Rodenberg in Dortmund-Aplerbeck originally emerged from a medieval moated castle on the banks of the Emscher and was mentioned in a document as early as 1290. Of the former gardens, only the outer bailey island, the surrounding moats, the house pond and remnants of the wall surrounding the main garden remain. Today the park area is a public green space in the center of the Aplerbeck district.

The current buildings were built as an outer bailey between 1920 and 1922 in the historicist style and served as the administration building for the steelworks. Hörde Castle and with it Ministeriale Albert I von Hörde are first mentioned in a document from Emperor Otto IV (HRR) in favor of the Corvey Monastery. The historically significant castle tower, which has been preserved to this day, dates from this period. After the decline of the steel industry on Phoenix East and the dismantling of the steelworks, a comprehensive renovation of the castle began in June 2008. After the excavations were completed in 2009, the numerous finds and some relics from the “Hoesch era” were exhibited on the ground floor of the castle building. The former Hoesch administration with the extension buildings is listed as an architectural monument, and the traces of the medieval castle are registered as an archaeological monument in the city of Dortmund's list of monuments.

The Rodenberg House is a moated castle in the Aplerbeck district of Dortmund. The castle fell into disrepair in the 19th and 20th centuries. All that remained of the former moated castle was the outer bailey with the economic section. After the castle was destroyed in the Clevisch-Märkischen succession dispute in 1422, it was rebuilt in the years that followed. Between 1689 and 1698 the castle was rebuilt into a baroque moated castle. The property was sold to the city of Dortmund in 1985, which had the park and Rodenberg house thoroughly restored by 1996 and finally handed it over to the citizens of Dortmund. The castle is listed as a monument, the former castle as a monument in the monument list of the city of Dortmund. Today, Haus Rodenberg is home to the seminar rooms of the adult education center in Dortmund, the fairytale stage (a puppet theater for children and adults) and upscale gastronomy. The premises of Haus Rodenberg can be rented for so-called ambience weddings through the adult education center in Dortmund. The former mill pond and the park with "orchard" are well visited in summer.
