The original coat of arms of Nigtevecht, using blue and white, seems to date back to the 1600s. The coat of arms with white and blue was used as a heart shield on the Huydecoper van Nigtevecht family coat of arms since 1721.
An unconfirmed story claims that when two families merged through marriage, they had the same colours but in opposite order. I found no evidence for this. However, there was indeed a dispute over the colours, eventually settled as blue-white. I found no record linking "Huydecoper Heer van Nigtevecht" (the Lordship) or "Huydecoper van Nigtevecht" as a connection between two families. It is unclear how the name "Huydecoper van Nigtevecht" emerged as a full name in some records. It was originally a lordship title (in Dutch: "Heerschap") and also a knightly title (Jonkheer, Young Lord). The title under the larger coat of arms reads: "The Liberties of Edw Huydecoper van Nigtevecht", rather than "The Liberties of Edw Huydecoper Lord of Nigtevecht", though this may be equivalent due to heraldic title usage.
It is clear that the Huydecoper family used a coat of arms with the left side blue and the right side yellow above black, pointing to the “Huydecoper van Nigtevecht” title. The family acquired the Lordship of Nigtevecht in 1721 and added the white-blue coat of arms, the opposite of Nigtevecht’s blue-white coat of arms. The origin of these variants is unclear. It is not entirely clear what happened; historical details may be unreleased or hidden in undiscovered archives.
The coat of arms with the crown was registered in 1950 and officially granted on 14 August 1976. After the merger of municipalities, this coat of arms was abandoned in 1986. The original Nigtevecht coat of arms may still be visible in the village of Nigtevecht on an old building. There is also an old fort called Nigtevecht, built in 1903 as part of the Defence Line of Amsterdam. It is a small village but with an interesting and important history.
