Couwelaar Castle, also known as De Drie Torekens (The Three Turrets) is L-shaped and consists of a main building with wings, as well as several outbuildings including a coach house. The main building is characterized by two round towers at the front and a built-in, square tower at the rear. Over the centuries, the castle has been extensively altered and restored several times and has stylistic elements of the Neo-Renaissance and Rococo, among others. Couwelaar Castle is a historical monument.
The first mentions of a Couwelaar estate date to the beginning of the 15th century: in 1402 it is recorded as belonging to Pieter van Immerseel. It later passed to Pieter de Francques, a merchant from Antwerp, and then to his son Raphaël. In 1584, Couwelaar was sold in the Vrijdagmarkt. In any event, in 1606 it was owned by Gilles Du Mont, a cloth merchant who had also recently acquired the nearby castle of Bisschoppenhof. The Du Monts significantly improved the castle by adding six towers and laying out gardens and fish ponds.
Couwelaar changed hands several times in the following years. Pedro de Man, a former schepen (alderman) of Antwerp, had the castle thoroughly restored in 1766, in classical style. Four of the towers were in poor repair and were demolished and a new moat, among other things, was added. In 1848, a pleasure garden in the style of the Italian Neo-Renaissance was commissioned by John della Faille de Leverghem and his wife, who had purchased the castle two years earlier. They also had the castle itself renovated in the style of the Flemish Neo-Renaissance.
The real estate company Crédit Foncier d'Anvers acquired the castle in 1913 and had the moats filled in. In 1927, the castle ultimately became the property of the municipality, which until 1970 used it for administrative services and as a workshop and storage. Repairs were carried out in 1986–88, particularly to the towers and roofs. In the early 21st century the castle was sold to a group of new owners who pledged to restore it without impairing its historic character, and it has been divided into five cohousing apartments.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
