The Grotto of Poelk, located at the intersection of Grotstraat and Omloopstraat in the hamlet of Poelk (Roosdaal), is a Marian grotto that is a replica of the famous grotto in Lourdes. Founded in the 19th century by local residents, the grotto was built with sandstone from a demolished castle in the area and the statue of Mary was given a prominent place thanks to a donation from the family of mayor Frans Tondeurs. Since its foundation, the grotto has been a popular place of pilgrimage, where candle processions and Eucharistic celebrations take place every year in May, especially on Ascension Day.

The English Bridge with accompanying cave is located west of the plant palace on Wemmel territory. It was probably realized in the period 1805-1810, when this area was laid out as an English garden, probably after a design by François Verly (1760-1822). In any case, it is indicated on the primitive land registry plan of Wemmel (1821). On the outside, the whole is finished with sandstone tubers, today heavily overgrown with ivy. In the southern side wall of the segmental arch bridge there is a marble high relief presumably representing the resurrection of the phoenix. On the other side a coat of arms with the mention Bon devoir gaigne. Above the entrance to the cave, a coat of arms overgrown with the coat of arms of the Roose family, who were responsible for the English landscaping. (Inventory of Immovable Heritage)
