Neder-Heembeek

Gazing upon Neder-Heembeek, it’s hard to imagine this bustling Brussels neighborhood was once a quiet village on the edge of medieval Brussels. Neder-Heembeek’s story is interwoven with its two historic churches. Originally, a single small church served a unified Heembeek. As the community grew, a second church arose in the north. This division led to two distinct parishes and villages: Over-Heembeek (Upper Heembeek) with St. Nicholas Church and Neder-Heembeek (Lower Heembeek) centered around St. Peter and St. Paul Church. Both parishes came under the ownership of Dieleghem Abbey in the 12th century. In the 15th century, Neder-Heembeek’s castle belonged to the Goudenaken family. Through marriage, it passed to the influential Busleyden family in 1505, remaining in their possession for over a century. The castle’s ownership changed hands several times, eventually being sold to Dieleghem Abbey in 1674. Neder-Heembeek also holds a unique place in scientific history. Around 1618, physician Jan van Helmont, a follower of Paracelsus, lived near the church. One night, a mysterious visitor, possibly linked to historical events of 1568, gave van Helmont a strange powder. This powder, when mixed with mercury, transformed into gold. This encounter sparked van Helmont’s interest in scientific processes. He became a founder of modern chemistry. In a strange twist, the same farm later housed Count Gioacchino Pecci, the future Pope Leo XIII, in 1843. Neder-Heembeek and Over-Heembeek finally merged in 1814, creating the single municipality of Neder-Over-Heembeek. The name preserved the identities of the original parishes. In 1921, Neder-Over-Heembeek, along with Haren and Laken, became part of the City of Brussels. This expansion significantly increased the size of the Belgian capital. Today, “Heembeek” is often used to denote various services in the area, overlooking the historic distinctions between the two original villages. Neder-Heembeek offers a fascinating glimpse into the layered history of Brussels, from its medieval origins to its role in shaping modern science.
