After the gruesome murder of the last owner, Baroness Thérèse Ernst de Bunswyck, the municipality purchased part of the estate, including the castle, which now serves as Boutersem's town hall. Other lots went to different owners, so the heritage's unity is somewhat lost, with several buildings besides the castle itself. However, there's much more than meets the eye.

The castle's core dates back to 1718, modified several times during the 19th century, and eclectically renovated after 1922; the castle and its outbuildings are surrounded by a 16.5-hectare park, originally a high courtyard with a watermill and mill pond; a classic 18th-century valley floor site, redeveloped in an early landscape style around 1830-1835; redeveloped around 1900 in a late landscape style; municipally owned since 1980; ice and vegetable cellars, numerous old trees.

The core of Horst Castle probably dates back to the 13th century and is characterised by a square keep. The keep probably belonged to the oldest core that was further expanded into a fortified castle in the 15th century. During the troubles under Maximilian of Austria in 1489, the castle of Horst was taken by the people of Leuven and set on fire. According to literary sources, only the keep, part of the entrance gate and a defensive wall remained standing. The residential and east wing were renovated and expanded in the 16th century. The round tower also dates from this period. The outer wall was provided with a rectangular bay window. The castle lost its military character and became more of a pleasant residential area with a view of the moat, the ponds and the inner courtyard. Brick construction with sandstone layers characterise these buildings. In 1587, however, the castle was set on fire again during the raids of the Geuzen. It was not until the beginning of the 17th century that restoration work began. It is difficult to deduce from the available sources to what extent this involved restoration or an embellishing conversion of the castle complex. Presumably nothing changed in the internal structure, but only after the structurally necessary repairs were the interiors completely refinished. Maria-Anna Van den Tympel had a new chapel built against the keep in the 17th century. At the beginning of the 19th century, the complex must have been damaged by plundering and neglect, and it is possible that it also suffered from plundering during the Brabant Revolution of 1830. Around 1850, the castle must have been habitable again, but the castle buildings only served as a farm. In the land registry, the site around the castle is called "De Notelaren Boomgaerd". Around that time, the most dilapidated part must have been demolished, namely the southern part and the superstructure of the gate. The rest of the complex was probably restored with reused demolition material and in traditional style. The castle was divided in 1880, with one part being registered as a school house. In 1897, a further division followed, with two plots being designated as houses. Several restoration campaigns followed in the 20th century.

Since December, there has been a spire on the castle again after the unstable spire was removed more than four years ago and could be viewed on a wooden platform in the pond. Now it is back. And the other works are also progressing quickly. More about the replaced spire on https://www.vrt.be/vrtnws/nl/2024/12/10/torenspits-staat-weer-op-kasteel-van-horst-holsbeek/

The Donjon Ter Heyden, also known as the tower of Ter Heyden, is a residential tower in the Belgian town of Rotselaar (province of Flemish Brabant) from the mid-fourteenth century. The donjon was built between 1350 and 1363 by order of Gerard van der Heyden, the then bailiff of the Duchy of Brabant, when he acquired the status and funds through a marriage with a noblewoman to erect a building of such calibre.

The watermill at Arenberg Castle was probably rebuilt around 1636 on a watermill site known before 1286, which was then equipped with two waterwheels. Major repairs were carried out on the locks around 1722-23 and 1733-35, and images of the mill also indicate modifications to the mill building in the 18th century. Around 1875, the watermill underwent a facade restoration and extension according to the then prevailing views, under the direction of architect Claes. At the same time (1870-80), the mill was equipped with a new bluestone lock and two wooden waterwheels. The waterwheels were replaced by metal wheels at the end of the 19th century, and the locks were also modified in the early 20th century. In 1940, the mill was demolished and the mill was converted into a drawing room; externally the mill was preserved, as well as the lock and the two water wheels.
