A walled and hedged cemetery surrounds the parish church. The brick cemetery wall on a natural stone plinth is capped with a bluestone coping stone. Both the iron gates above the brick wall and the entrance gate hang from brick gate pillars with a bluestone capping. A pedestrian passageway runs to the left and right of the entrance gate. An undated natural stone cross has been incorporated into the north wall. The historic cemetery contains a series of gravestones from the interwar and postwar periods. They are designed in a sober Art Deco and Modernist style. The gravestones evolve from bluestone to (multicolored) composite stone, mosaic, synthetic material, natural stone, and granite, thus demonstrating the shift in material use between 1960 and 1980. Several epitaphs are placed on marble slabs. Near the entrance is a plot dedicated to Belgian veterans, marked by identical bluestone crosses bearing the Belgian flag. The cemetery expansion, dating from the 1990s, primarily includes granite headstones. The flowerbeds are bordered by clipped hedges and clipped hornbeam volumes. The shift towards ash burials is clearly visible in the newly created scattering meadow and urn vaults.

Church built of sandstone; the floor plan unfolds with a west tower, three naves of three bays, a projecting transept, and a long choir ending in a three-sided apse. Square Gothic tower with three stories dating from the second half of the 13th century; ground floor covered with heavy rib vaults resting on roughly worked corbels; pointed arch towards the nave; upper floor perhaps formerly equipped with a tribune (currently in neo-style); bell storey with decorated sound holes in the east and south facades; rectangular, partially renovated wall openings in the other sides; oculus from the 18th century and neo-Gothic portal on the south side. Nave and transept from the same period, covered with a steep roof in late Gothic style (16th century); brick vaulting in the transepts, but wooden pointed barrel vaulting in the nave. Light corner buttresses against the shouldered gables of the transept arms; the arcade and northeast half-column are possibly older and built together with the choir. Western choir bay covered with a pointed barrel vault (late 15th century); closed-off and blind eastern section in a less developed Gothic style (13th or 14th century), partially rebuilt of iron sandstone in large and regular bond; new window in the north; the date 1731 on the choir apse probably indicates a restoration. Furniture. In the transepts, paintings by Verhaghen (late 18th century); Romanesque baptismal font decorated with four heads (12th century) and a Gothic holy water font (16th century).

Duke Charles III de Croy (1560-1612) had the Arenberg Castle moated, the park laid out and the avenue to Leuven extended at the end of the 16th century. A memorial stone was built into the right side wall of the Cantine to commemorate the construction of the avenue to Leuven in 1596. In the 18th century, when the castle and the park were owned by the Arenberg family, the entire domain was enclosed by a wall. The moat around the castle was also filled in. This resulted in a significant change to the terrain, which was originally very marshy. Nevertheless, the structure that Charles III de Croy gave to the landscape around 1600 is still clearly recognisable. The whole of gardens, orchards and outbuildings was then arranged around two main axes, which corresponded to the axes of the castle: an (approximately) north-south avenue, from the Terbank leper colony to the Meerdaal forest that served the Croys as a private hunting domain, and an east-west avenue, which extended from the Celestine Priory, the Croys' family mausoleum, past the new stable buildings to the entrance gate right on the city walls, opposite the Namur Gate. The construction of these straight avenues, bordered by palisades, for kilometres long, had forced the Duke to purchase important land and then to carry out major earthworks: hills were dug away – such as the hill on which the old Romanesque Saint-Lambert church stood, which was desecrated as a result – and holes and pits were filled in. Duke Charles Marie Raymond of Arenberg had a ‘jardin anglois’ built in 1771 to his own design, with the Yellow House as the focal point of the picturesque garden, a pavilion on a hill to the southeast of the castle, and with many remarkable exotic tree species such as a Lebanon cedar (Cedrus libanii) that was brought over from Edingen. The historical value of the Arenberg Park is formed by the connection with the Arenberg Castle and the other buildings located there.
