Bristol Hercules XVI engine monument The engine is aimed at the place of crash, in the meadow behind the parking lot (behind the trees).

The engine comes from the Vickers Wellington bomber with the registration number HE727 and the “call sign “NA-K that crashed in Wilnis on the night of 4 to 5 May 1943. This engine was found during the salvage of the aircraft in 2002. It is a 14 cylinder two row radial engine with a power of 1675 hp. The engine was produced by the Bristol Aerospace Company in England and designed by Roy Fedden. Bristol Hercules engines were used in several British aircraft types during the Second World War, including the Lancaster and the Halifax, both four-engine bombers and the Beaufighter, a twin-engine bomber.

The engine was exhibited in the former Museum De Ronde Venen, but after the closure of the museum the engine ended up in storage. On the initiative of the Historical Society De Proosdijlanden, the engine was restored and treated against weather influences. On Thursday, September 26, 2019, the engine was placed here and unveiled by Maarten Divendal, mayor of De Ronde Venen.

In memory Piet Kroon (1939-2020)

On July 4, 2020, the man who did so much to give the fallen Canadian soldiers a dignified grave passed away.
Thanks in part to his great effort, the Vickers Wellington was solvaged in 2002 and the bodies of the crew members exhumed.
The fact that we can now also see the engine is also thanks to Piet.
Rest in peace.
