The cemetery surrounding the church is well worth a visit, both for its local history and the many old graves and headstones. Behind the last grave is the motte and bailey of Néthen, which, especially nowadays, seems simply a forest. Diagonally across from the front of the church is the castle of Zeebroeck. The family's burial chapel is built against the rear of the church (and is accessible).

In 990, exactly 10 years after the founding of Brussels, Count Arnould de Brugeron granted the allodium of Néthen, located in the Duchy of Brabant, to the Chapter of Saint Jean l'Evangéliste in Liège by charter. This document, over a thousand years old, which first mentions the village's name (Néthene), mentions that there are two churches in Néthen: one in Wez (Bas-Néthen) and one in the town center (Haut-Néthen). The Chapelle de la Motte, a castle chapel, was given the title of parish church after the Battle of Hoegaarden in 1013. After this battle, the County of Brugeron came into the possession of the Dukes of Brabant. No iconographic documents exist of the original church. The church was restored in 1539 and was then only a modest Gothic oratory with a pointed spire. From that time on, it bears the name Saint Jean-Baptiste. Due to the poor condition of this oratory, it was decided in 1767 to build a new church on the same site, partly using materials from the old church, but also from the chapel of Notre-Dame du Wez, dedicated to Saint Nicholas, which was demolished in 1767. 1757. This current church was rebuilt on virtually the same site as the first. It faces northeast. During the reconstruction in 1768, the foundation had to be raised by two meters in some places to prevent the church and cemetery from frequently being flooded during heavy rainfall by water flowing from the fields of Pécrot and La Malaise. At the rear of the church is a remnant of one of the three fortified towers built to protect against the Counts of Leuven. The other two towers were located in the Savenel and Broux (Pécrot) estate.

From this location, you actually have a view of the church. The church itself and the unique cemetery can be found a little further along Rue de Bossut (which intersects Rue de Hamme-Mille here), opposite the 'Zeebroeck Castle' – see https://www.komoot.com/nl-nl/highlight/7679340 The church itself, with description, photos, and the correct location, can be found at https://www.komoot.com/nl-nl/highlight/4080868

The start at the top is somewhat hidden between the houses. Nice unpaved alternative to the 'regular' asphalt descent.

You have several trails here. Make no mistake. The main trail is S1 but there is also an S3 trail hidden by the ferns
